From the description it looks like this bug is purely server side and
could for example happen if client lost internet connection during
ubercharge - introducing VAC here is only going to hinder finding and
fixing server bugs and possibly ban innocent users.

The way I see it, it's as much of a bug as wallhacking is.
Things like these are why we need a new, revised VAC, which actually
poses a threat to cheaters now that TF2 is F2P.

BTW, Evan added me on Steam to discuss this. Not going to reveal too
much to avoid someone using the exploit with bad intentions.
He said that yes, the not sending usercmds part was right. But, as
some of you would remember, Valve fixed a bug where Medics could
infinitely uber themselves, but infinitely ubering someone else wasn't
fixed. Currently, the client handles the timing of ubercharges. They
end when powerplaytime < clientticktime. clientticktime is only
updated when the client sends a usercmd. No usercmds being sent means
infinite ubercharges.
Packet manipulation could be used, among other methods which I won't
reveal.
