Probably be good to allow ZLE if there's away of doing it, yes.

From what you're saying, two decades of behaviour haven't done anyone
much use at all when combining -i and -s --- the -s is effectively
ignroed.  So actually I don't think it's all that crucial as long as the
only changes are where both are given, which is what you're suggesting:

-s being the part of the business that has been ignored, it's hard to
see how making it take precedence now can break anything that was
working and that logically should have worked.  So it all sounds fine
to me.
