We've got a mod for that anyway, the V-Script update stuff was a massive boon for this game.

And those who don't like L4D2-isms can just straight up mod the whole thing to be more like L4D1 across the whole gamut, and play the classic campaign mode or versus setup where only the first game's items and special infected spawn. At this point one can say 2 was kind of a shitty thing thematically compared to 1, but there's no point to hold any grudges about it.
