It cannot be generalized like that. When deciding where to store files,
one must tell what type of files they are. Skimming over the FHS can help
to find the proper location, as the packaging for Fedora can get a lot
more trouble-some, if a software project installs into uncommon locations
or violates the FHS even. /usr/share/ is for architecture-independent
read-only data files.

/usr/bin sounds reasonable.

At least, it should be easily possible for your project to store small
scripts in /usr/bin, which know about their home directory, from where to
load supporting files (including additional hidden scripts not to make
available in $PATH).

That sounds a bit like a design mistake. Can you tell why you think you
would need a directory structure below /usr/bin and not elsewhere?

That's inaccurate. Adjusting $PATH via profile.d scripts is a good
solution for *some* projects, e.g "ccache", but it ought to be an exception
(and there's a reason why "ccache" does it like that). It doesn't sound
correct/ideal/elegant for your scripts.

As above, a design mistake?

The scripts would stay in /usr/bin, be available for execution by every
user, and if you moved anything at all with an update of the software in
an update of the RPM package, you would replace the script files. Why would
the new files not work anymore (or not know about changed directories)?

Perhaps you could explain in more detail what problem you're trying to
solve?

That's not unusual.
