Yes we should, actually. It stands for defense independent pitching
stats. If we include hits in play, it's no longer defense independent, no
matter how we choose to estimate the defenses contribution. It goes from
DIPS to PS.

The point I'm making is that there's a price to be paid by multiplying
things by a series of weights and balances. The numbers cease to mean
anything other than a best guess as to how good the pitcher was.

IOW, even if pitchers had a meaningful ability to affect hits per balls
in play (which they don't), DIPS would be a solid concept (in fact I
started putting them together before I knew the first part), if only for
use in evaluating teams.
