I agree that this feature is pretty esoteric and probably more cognitive
load than it's worth. One of your use cases has workarounds shown below.

Doesn't specifying an explicit URL get around the refspecs configured
for the remote? E.g.,
git fetch $(git config remote.github.url) master
Or if we had a way to temporarily unset multivalued configuration values
(which we may have soon thanks to the GSoC project of Tanay Abhra), one
could use
git --unset=remote.github.fetch fetch github master

I'm not quite sure what your goal is here, but if you want to fetch some
branches on the fly without setting up a remote, then
git -c remote.github.fetch='refs/heads/*:refs/remotes/jch/*' \
fetch https://github.com/gitster/git maint master next +pu
should work, no?
