OK, that's a reasonable counter-argument to my patch.
} In the early days, _comp_options was intentionally kept minimal.

There would be a case for wrapping the "eval" expressions in _expand
with temporary restoration of $_comp_caller_options, because of the
effects of NO_ksharrays etc. There might be a few other similar
} The quoting is internal to the C code so shouldn't look at
} _comp_caller_options. We'd need to add some sort of hook
We have the "sticky emulation" mechanism. Entry to completion could
save the current option state before invoking the user-defined code,
and then compadd could temporarily revert to that saved state. We
could also add another builtin (compopts?) to manage it explicitly,
though the state would still need initial capture.
On a side note, maybe we need a special keyword for "emulate" that
means "make sticky whatever the current options are" -- right now
you would have to spell that out explicitly, relative to some base
emulation such as zsh or sh.
