Why is this a problem?
Consider the backswing on that quarterstaff. I'm not going to bother looking up the algorithm and doing the math, but the backswing weapon might up the staff's PV beyond where it'd be if he just increased the speed rating (and thus had the same attack rate, but with all of them at a full 5 DC).
For a staff, that won't much matter, since it's cheap. But consider a stun setting for an expensive weapon, implemented as an integral subcomponent. That could be very expensive (thus monetary cost) and significantly cut your combat XP, thus slowing character growth. And you get no added combat effectiveness for it, either (which is presumably the reason that PV affects XP).
So all I meant was that there's a potential problem with his example, given the game mechanics.
IIRC I had trouble modding in a combination weapon once upon a time. I think one had to wait until the other was ready to fire before it could be fired. So an integral grenade launcher might not be able to fire between assault rifle bursts, or whatever. If your backswing's working flawlessly then either that's changed or my memory is as clear as a ton of bricks.
