True.

If the helpers are roughly interchangeable (that is, if you can switch
between fetching using each one into the same on-disk git repository),
then picking one to symlink as git-remote-hg in your $PATH should be
enough.

If they don't have that level of interoperability, then there's an
argument to be made that the URLs shouldn't be the same.
Unfortunately url.*.insteadof rules are resolved at fetch time instead
of being resolved once and the result recorded in .git/config.  So
yes, it seems like a way to have abbreviations for URLs (e.g., hg::
meaning hg+mh:: or hg+fc::) that get resolved at clone time would be
useful.  It's a layer of indirection we don't provide. :/
