Really, I see not much value in supporting more than one kernel. That
just means reinventing the wheel over and over. If others care, fine
for them.

This is bogus. There is no dependency on rtkit here. if during runtime
the rtkit service is found it is used. If it is not found it isn't
used. end of story.

There is not compile time dependency on rtkit and no runtime
dependency either.

If I had introduced my own little library everyone would have to link
to it. However this way they just have to depend on dbus, which is
something many applications link to any way. So this way there is many
cae no dependency added at all. And the build is certainly easier.

Also, the client reference implementation is tiny. it just wraps two
method calls. Trivial stuff.

Then file a bug.

The .c/.h files are pretty explicit. Ever single file one has the
GPLv2+ blurb in it.
