To requote Kent, who has probably used this the most, "I've been running 
with maildir on IMAP for several months now with no issues."

But best to judge for yourself what may or may not affect you, by 
digging in to bugzilla (you can edit to suit your 
requirements). There are 5 dataloss bugs there. Two of which are fixed. 
The other 3 may or may not affect you.
