No idea about that ... I doubt there have been any imake changes
that would affect something like that.

Well, before a library would be considered for inclusion in Red Hat:

 - There would have to be some serious application of the library
   to demonstrate that it actually meets the purposes it was
   desired for.

 - (Usually) something else in the distribution would need to require
   it. The supported devel platform for Red Hat is a small subset
   of the libraries we ship as dependencies of apps.
 
 - The authors of the library would have to express confidence that
   the ABI/API of the library is something that will be supported
   long term.

None of these are there yet for Xr/Xc. I suspect Xr/Xc can progress
quickly, but putting it into a distribution prematurely wouldn't
help.

If someone wants to use Xr/Xc for a SVG renderer, then they need to
try writing their SVG renderer and figure out what's missing. There
are some pretty obvious gaps currently. (Like the ability to render
and get access to the pixels client side, which you need for SVG
filters.)
