I did the switch from mainstream to dovecot repo to upgrade from 2.2 to 2.3 on xenial, and appart one or two minor configurations changes, it worked just fine.

And more recently, I switched from a bionic-backport of cosmic release (used to get 2.3 on bionic) to this just released version using apt and it was transparent.

In my case, switching back to mainstream on the other hand would be harder, as I now rely on 2.3 specific features.

So I guess as long as you don't use features that are not yet released upstream, switching back should not be difficult.
