MLM not needed, as it uses the Britz?
Where are you getting all this from. I am yet to find a reference to use of a phase IV? The first list is from Mr. Krebs website and as far as I can tell was simply based on dates and assumption phase IV would be flying by now. And yes there is both an unaccounted Proton-K and Blok-DM, but the Proton-K would have passed its shelf-life by now? If I was to guess I'd say the next generation of Briz-M has already flown with Intelsat-22.

Initially there was just the enhanced Proton; documentation of that time makes no reference to a ‘phase’.The failure of the Proton-M with JCSat-11 lead to the closure of the 74·5° launch azimuth.It appears Phase IV is about regaining that lost capacity?

Stan I think is referring to the "74·5° launch azimuth" as 74·5° towards the equator, which was subsequently banned from future use by Kazakhstan officials. Russian officials had to accept the permanent ban of the 74·5° launch azimuth by Kazakh officials in order to resume launching from Baikonur Cosmodrome.

“Nominal Mission Lifetime” means, with respect to the Express AM4R Satellite, (based upon a Proton phase 4 performance) a period of 15 (fifteen) years after completion of the Final or Provisional Acceptance of the Satellite in orbit (whichever occurs first).

For Glonass or DM-03 upper stage, which Phase Proton is used?
Quote from: Danderman on 01/01/2014 10:11 pmFor Glonass or DM-03 upper stage, which Phase Proton is used?Up to now only the Proton-M phase I has been used with DM type upper stage. [further details]The latest missions feature the RD-276 on the first stage, in place of the RD-275. It is possible the RD-276 were not operated at full throttle. However Proton-M Briz-M (and also maybe Proton-K Briz-M) operated the RD-275 at a slight increase of 2%; so not sure what thrust they run at. [further details]It is also to be noted that some Proton-M phase I missions with DM upper stage, sported a white fairing. A white fairing made it’s appearance as part of the phase III upgrades, so are these DM fairings also with ‘improved energy-mass characteristics’?
The satellite, Intelsat DLA-2, also known as Intelsat 31, will be launched by ILS Proton in 2015 from the Baikonur Cosmodrome in Kazakhstan utilising the vehicle’s Phase IV performance capability.
Looks like the serial numbers start from 93701.
Also to note that Proton-M have serial numbers up to 93576; so at least another twenty phase III?
93701/99570 Intelsat 3193702/99571 EchoStar 2193703/99572 AsiaSat 9
19 February 2016AsiaSat has successfully completed the launch vehicle PDR for AsiaSat 9 in Moscow at Khrunichev facility. AsiaSat 9 will be launched using the upgraded, higher capability Phase IV Proton-M rocket with Breeze M upper stage. The upgraded Phase IV Proton-M rocket has been qualified to provide a higher performance lift capability for AsiaSat 9. This includes lighter structure, better propellant management and other associated improvements. The upgraded launch vehicle performance will provide AsiaSat 9 with more fuel margin to exceed the planned in-orbit maneuver life.
We now have the capability to essentially roll back to prior configurations that will provide the necessary performance for these lighter satellites while taking advantage of the cost effectiveness from the technology introduced to improve the vehicle performance over the past 10 years.
So, the introduction of phase IV does not indicate the end of phase III or even phase I?QuoteWe now have the capability to essentially roll back to prior configurations that will provide the necessary performance for these lighter satellites while taking advantage of the cost effectiveness from the technology introduced to improve the vehicle performance over the past 10 years.http://www.ilslaunch.com/node/4592
Translated to English via the owner/staff at Russian Space Web:QuoteOn January 30, the head of RKTs Progress Dmitry Baranov was quoted by the official TASS news agency as promising "around 20" launches of Soyuz rockets during 2023. With two or three Proton launches and couple of Angara missions, Russia could make more than two dozen orbital launch attempts during the year.
