Well, some interesting points for discussion here.

First, I'm pleased they show the relative minor as a choice of key signature. I want to know where the root is, not just the key signature.

Second, I would be OK with eliminating impractical key signatures like A#, but maybe there is someone out there who wants this, and having it can't hurt if you don't use it.

Just to be sure, going around the circle of fifths, where would you suggest drawing the line? At F# / Gb, or would you, say, allow one more in either direction: Db or B, since these are possible to be written as seven sharps or seven flats, respectively? Another way to say that is, perhaps you don't want the possibility of double sharps or double flats?

As an aside, the staff at PG Music includes some very fine musicians.
