This has annoyed me for ages, I'm glad progress is finally being made.

IMO this isn't enough of a solution. First, conf.d isn't adequately
descriptive even when it's in a ganglia directory because the files
actually only apply to to gmond. Second, I continue to believe that
having the ganglia directory at all has never made sense. Historically
we've had exactly two, well defined config files so I've never seen a
compelling need for a ganglia directory. On the FreeBSD port we just
have gmond.conf and gmetad.conf that live in ${prefix}/etc. I propose
that we rename conf.d to gmond.conf.d.
Also, when I was looking, it appears that ${sysconfdir}/conf.d is
hard coded. It seems to me that we'd be better served by a config
include directive similar to the one in Apache.
