That's not necessary.

IMAP servers never see the new flags; only c-client sees them.  If
they are passed to older versions of c-client, they will be silently
ignored.  So they are safe in all cases.

The new flags are transparent to all servers; they do not change the
IMAP protocol language itself.  The flags only improve the grammar and
coherency of clients speaking the language.  Yo!  :-)

For purposes of the IMP project, the only people who need to know
about the new flags are developers working on php_imap.c.  And their
only concern is that code restructured to use the new flags with any
c-client search or fetch functions must anticipate either old or new
behavior from the c-client function calls.

If you make imap-2001 c-client a prerequisite for future versions of
php-imap, then you can ignore the possibility of old c-client behavior
when working on new code for php_imap.c.  That might be a good idea in
the not too distant future.

Yes.
