Much agreed. Once you modify the back-end files of anything upgrading becomes a nightmare b/c the upgrades usually will overwrite the mod's added.
I'm currently running a decently active phpBB but, keeping it at 2.0.1 because I really don't want to bother to go through and re-add the mods and personal hacks already done.
I'm waiting until a big update comes through to even bother touching it.
