This appears redundant, given that there's already $PATH which pretty
much does this. I think instead of the above there should be a brief
comment, that $PATH is the search counterpart here...

A problem with ~/.local/bin is that $HOME might be shared between
systems of different archs, and thus any compiled binaries dropped in
this dir might cause problems when used from other systems. I don't
think this issue is reason enough not to have ~/.local/bin, in
particular as many distros and systems already have it and it is a
good idea to document what is already established, but I am very sure
the spec should document the issue at least, and maybe suggests that
scripts rather than arch-specific binaries are preferably placed
there, or that if arch-specific binaries are placed there $HOME
becomes arch-specific to some degree, which is probably not even a
problem in 99.9% of the cases, and hence acceptable in the local case.
