Though nice to see progress, article seems to lack mention of price or re-use.

Do they have any customers for AR-1?

Even though not officially declared, Are they still hoping to make some kind of "Atlas VI" where RD-180 is replaced with two AR-1's ?

They recently chose to go with in house Reaver-2 and Reaver Vacuum Engines for Beta. It is now only on the table for Gamma.

And was for fully cryogenic/storable green propellants for stage 1.

Doesn't stop LM building their own version.

Yes it does. LM's business model (like all primes) is making money from US government contracts and standard commercial products. Building their own XS-1 without a customer is not going to happen.
