I do feel this is important, because it is the way parts were meant to work... In the event a part is denied, a user would be unable to reopen the window (the server would deny the join, because the user would already be on that channel)
How can it be the way PARTs were meant to work? PARTs were never meant to be disallowable! And as far as I'm aware the only IRC daemon that attempts to prevent a PART is UnrealIRCd. That's where the fix needs to be made.
