From the user perspective - yes.

We could have a module to handle operations on PATH which would include
a function to append/prepend a list of paths and then start some
function or code with a path set-up. I know this would be a major change
though. Other solution is exec-path to be just additional set of the
directories that we pre-pend to the PATH.  In both cases however we'd
lose ability to amend the environment which might be not desirable I
agree.

Thanks,
