Hi Rob,
IMHO, the crap of vendors that you mentioned is very real and, it is
largely caused by -and not causing-
lack of a single place for applying environment tuning/control. Compare
bash vs zsh:

have similar diagram for your distro, please post!
fi. HPC systems rely on environment modules [1] and bash is still
particularly tricky while using it, after 2 decades :-( .
Users on large platforms flee towards other shells (in practice: that's
zsh) due to this sticky issue,
which is certainly fixable and, we might even get a chance to fix some of
bash_logout's annoyances, too.

[1] environment modules is a well tried technology, first appearing in year
1991! ;
if you have ever cought yourself to have a messy bash initialization
file, check it out because it really helps.
In fact, with it you could have most of the common configuration for a
handful of shells *in a single place*.
