This is probably most likely, far several reasons:

1. DPS implementations (DGS, XFree DPS, ...) are not complete.
2. DPS is slow (even Adobe's DPS).
3. People will always want a fast, light solution.

Note that the only difference between the xgps and xdps backends is
graphics. All the window and event handling is the same. Whatever was
easy to implement with Xlib calls was put into xgps (in particular,
scalable and rotatable text is not implemented). I don't put a lot (well
almost no) time into improving it, but anyone can feel free to do so.

Any major improvements (for instance, using libart) might (or might not)
call for another backend...

Maybe the proper way to say it is a Display Postscript implementation
based on GS, but that's not exactly what Ralph was proposing - it was
more like having the ability to integrate ghostscript into (GNOME)
graphics via a drawing buffer (which would almost completely eliminate X
drawing calls and make it fairly fast). It's a pretty good idea anyway.
