A good point.

Another. We're not running into that one in our market (yet).

Perhaps not compatibility, strictly speaking, but we're going to miss
our old friends backing store and save unders. Their demise feels
like a breakage of compatibility, as the X servers we've used have all
had reasonably aggressive offering of the optimizations (til now).
(We have been strongly depending on their existence, incorrectly.)
One of our applications has a very expensive redraw cycle that we now
have to decide how we are going to manage when backing store is not
being supplied. This "extra work" at this point in time creates a
certain amount of frustration that I impolitely let show in my earlier
e-mail.
