Or just fixup the path in env-module config file. That's about the only
technical argument in favour of libexec. Using libexec doesn't require
hacking the config files.

GROMACS is an end-user app IIUC and its binaries are used directly.

It handles everything.

I don't think it is. That's certainly a way of thinking about env-modules
I haven't considered, but I think treating GROMACS binaries as "private"
of environment modules makes no sense. They have nothing to do with
env-modules and they are not private. Rather, env-modules is a convenient
way of allowing both gromacs3 and gromacs to be installed concurrently
and avoiding polluting %{_bindir}.
