They will probably keep the last version before the license change for a while, and probably add minor community-sourced patches.

The next version of ubuntu will include mongdb version "3.6.9+really3.6.8+90~g8e540c0b6d" which you can see means "last commit before the license change"

I can foresee the day when that version of MongoDB is advertised/discussed as having "AWS Document DB compatibility" (rather than today's converse).
