There appear to be two major things people are using DGA for that we don't 
currently have a good replacement for:

- Relative pointer motion (which we could probably add to XInput without much 
hassle, since all the drivers know how to report that anyway)
- Fast-ish drawing using "visuals" that don't match the screen's depth (which 
we have initial support for in fb, and which exa actually has a fighting 
chance of accelerating, unlike xaa)

If there are other uses besides these, I'd like to know.  Technically it's 
been "deprecated" for a long time, according to the man page.  It would be 
worth reminding people of this in the 7.0 release notes.
