I agree. I'd rather not see glxinfo and glxgears cluttered with this
kind of output.
I suspect the motivation here is to help diagnose end-user GL issues.
If so, I think it would be better to have a program designed for
that purpose. Such a program could set LIBGL_DEBUG=verbose, query DRI
info, etc. to report extra information. Even a simple shell script
that wraps glxinfo could do this and emit the diagnostic info in a
concise format.

Determining software rendering by the string is unreliable.
And the glXIsDirect just duplicates information listed before.
Furthermore, printing these warnings to stdout would be a very bad idea --
scripts which run glxinfo and parse could easily get confused by these messages.
Overall, I really don't see the benefit of doing any of this.
