I don't think so.  If you look at the IDLE option it says "(if
supported)".  Some server's don't support IDLE, so the user may want to
still poll [although at a *SANE* interval, *NOT* every minute].  Also
IDLE only is effective if the connection stays up [as it should, for at
least 30 minutes].  If the server or client closes the connection [1]
then IDLE can't work.  The same is true if the network is unreliable
[like a cellular connection] and the connection gets dropped.  So
setting the check-for-new mail to an interval like every-60-minutes
while having IDLE enabled makes sense.  IDLE works well [when supported]
and is very efficient, but the occasional poll is still required in most
cases.

[1] GMail used to do this a *lot* - GMail is *not* a real IMAP provider
- maybe they've fixed this - I don't know or care.
