Yes, absolutely! I can think of examples where both /usr/lib
and /usr/libexec have been used for "private" executables. I don't
have a strong preference for either -- I just want one to be chosen as
the "standard Fedora way" to handle the various use cases I described
earlier.

I'm against the inclusion of "environment-modules" in the path since
you don't *have* to use environment-modules to take advantage of the
multiple implementations or versions once they are made available. One
can always add the desired paths by hand or via ~/.bash_profile or
some other way.

The environment-variables system can and does (and is often used at
cluster and/or "supercomputer" sites) to handle all sorts of
environment variables including:
PATH, MANPATH, LD_LIBRARY_PATH, CFLAGS, LDFLAGS, etc.
The environment-modules can also depend upon each other (so using one
automatically pulls in all its dependencies). But that's another
topic...
