I don't quite understand the problem with having fewer PoBs.
There is no problem with fewer POBs.
There is a problem with demolishing people's beloved projects they poured lots of creativity and time into. Be it POB, roleplay character that happens to share a name with some guy in some movie nobody watched, or other.
There is an even bigger problem with doing so for no good reason.
The biggest problem of all, however, is that it almost seems as if not "quite understanding" something like this (more like, not caring enough for players to bother and try and understand it) is a prerequisite for being lifted into to glorious position of decision-making disco staff.
