I don't see the harm in leaving the option in, given that for some applications a longer passphrase is critical (not everything can use iterated hash schemes: for instance if you want to deniably encrypt a hard drive partition to look like random data).

EDIT: also, 'explicit' is a nice touch, makes some pretty memorable passphrases, but I hope you're not taking from a small list of profanities, since that would seriously diminish the entropy. Be sure to factor in the (probably) much smaller number of possible 'explicit' passphrases when doing entropy calculations.
