In addition, I would suspect (but don't know) that it's going to screw
up experienced painters who know how much they can paint with a
gallon.

Oh for crissakes people. No 2 "gallons" of colored paint contain the same
amount of paint. The base paint takes a certain volume. They have to leave
room for adding colorant in the store to make any color you want.
Experienced painters are going to be "screwed up" because they haven't ever
gotten an exact gallon in their lives, and they never expect to.
