Yes, but that has another downside: what's in a release tends to stick, for 
various reasons, including user take-up and developer acceptance.  At that 
point, the question becomes who likes the new thing and who doesn't, how many 
do and don't.  And such "polling" or debate typically favor the (new) status 
quo - it's in; leave it in.  "That ship has sailed" is a sea-shanty refrain we 
hear quite often here.
