It's not quite that clear cut. If installing on a system that has
bash-completion built and installed from source without any special
settings given, it will give a /usr/local directory for installing
completions, specifically
/usr/local/share/bash-completion/completions.

In any case, it will give the *correct* directory where to install the
completions to. If we (we = bash-completion) did have support for both
let's say /usr/share and /usr/local/share bash completions dirs, we'd
want to expose both of those through our *.pc and have people use it
to get the locations, but they'd need to be two variables and how
would the build system of let's say pulseaudio know which one to use
(assuming it wouldn't be asked from the user)?

Anyway, I don't think the possibility to install into system locations
if bash-completion.pc so says is an issue (and in any case it's a
smaller problem than installing into the deprecated and eagerly loaded
/etc/bash_completion.d), and I'm not convinced that adding another dir
where to load them from would be a clear improvement overall.

By the way, where to load completions from is a bash-completion (not
bash) thing, they're separate projects.
