I'm in no sense an authority, but here's my take:

Actually, despite the comment on extract_option() I don't see it being
called at RCPT. Maybe I'm missing something, or maybe the
comment needs correcting.

Given the limited number of callers I'd be happy with such a mod.
The problem is that it's still required for the current options,
and you've not determined what the option is yet.

I'd like a code refactor from the if/elseif chain into a table-driven
approach, using a static data table of acceptable option names
each with a "supplies argument" indicator. This would be in line
with (eg.) the parsing in acl_verify().
Admission: I've been a-refactoring in verify myself (bug 1184).
Good luck; it looks like a worthwhile project.
