Depends somewhat on how the server notifies other folders of changes
anyway.

I would disagree here.  I've not seen many imap clients which do a query
every time you scroll throuhg the list of messages; which is what they'd
have to do if they did no caching of flags.

But on the other hand, evolution doesn't rescan the flags every time you
switch folders, which it should, but is a big price to pay for people
who dont need it.
