Not really, no. The only one which fits that bill (implements
SwapBuffersWithDamage and is known to not always send infinite damage) is
PowerVR. However, the PVR implementations are third-party, not distributed by
Imagination themselves, so I think breaking those is completely fine: we're not
going to break anything by upgrading that no-one can fix.

Even then, the client winsys implementation on PowerVR can be implemented by
external modules, as it provides an API that lets you compile externally, even
when you don't have the DDK source.
