Your reasoning is now the other way around. Your initial point was: "what if ESA says no after EM-2". Your point is now: "what if Trump says no".Two very different things IMO.
Testing completed on Orion service module
Airbus wins EUR 200M ESA contract for 2d Service Module for NASA's Orion capsule; launch on NASA SLS in 2021. 1st model to fly in 2018.

ESA has 40 years experience with the Spacelab pressurised module Spacelab Spacehab Columbus MPLM Cygnus and probably some others I've forgotten.
The study of new propulsion options for the service module is being done because the module uses the space shuttle’s orbital maneuvering system (OMS) engine and its supply is limited. “There are propulsion trade-offs for how to enhance [the propulsion system] for the long-term,” Parker said Feb. 3.Parker expects the first three service modules to use the OMS, which uses the fuel monomethyl hydrazine and the oxidizer, nitrogen tetroxide and produces 6,000 pounds of thrust. ESA is considering four alternate engines, Dettman told SpaceNews in a Feb. 3 interview, but he declined to say which engines.

While ESA’s technical studies are ongoing, one possible European cislunar technology will go to the ISS this year. “[The] advanced crew life support system,” Parker explained, “has the potential to be one of the contributing technologies for deep space exploration”.

I am starting to figure out. NASA has mentioned in the past that it would like commercial companies to provide the module for the deep space habitat but that ECLSS might remain governmental. So the ECLSS could go to ESA under this plan.

I think that commercial crew and habitats go hand and hand.
From the article:QuoteThe study of new propulsion options for the service module is being done because the module uses the space shuttle’s orbital maneuvering system (OMS) engine and its supply is limited. “There are propulsion trade-offs for how to enhance [the propulsion system] for the long-term,” Parker said Feb. 3.Parker expects the first three service modules to use the OMS, which uses the fuel monomethyl hydrazine and the oxidizer, nitrogen tetroxide and produces 6,000 pounds of thrust. ESA is considering four alternate engines, Dettman told SpaceNews in a Feb. 3 interview, but he declined to say which engines.Which 4 engines could this be? The first two are easy to guess:1) AJ-10 derviate2) Aestus (used in the Ariane 5 EPS)3) ...?4) ...?
