The
requester clarified the request today:
So for example if the user removes the email address, or replaces it
with another but doesn't verify it, the user rights associated with
their user group are automatically suspended, until a verified email
address is provided, when they're automatically re-enabled.
I think this is already the case. If it's not, it's a bug.
"Sysops only have sysop powers if autoconfirmed" would be a bit hard to
configure but I think is also already possible.
That would not necessarily be a good idea. Enwiki has some adminbots that
only
perform deletions/protections/whatever and don't make any edits. They'd
never get autoconfirmed, unless the bot owner would do some otherwise
useless edits with them.
