Considering there are many focal lengths and lens types that users feel they're missing, what on earth is the point in so many short zooms?
First of all, they're not really "short" zooms: they all cover wide angle to short tele. (Remember, these are DA lenses for cropped sensors). So, when examining Pentax's lens line-up, one must always keep in mind the "35 mm equivalent" of the lens. When examined from that vantage point, users aren't missing that many focal lengths (current lineup covers -- in terms of 35 mm equivalent -- from ~15mm all the way to 375mm). The main"lens type" that Pentax users are missing (compared to the FA series), is the 250-600.
While there were more zooms in the FA series, many of them were in a range equivalent to 16-45, the 16-50, the 17-70, the 18-55 and the 18-250 DA zooms. It's the most popular range with consumers; and it's less expensive to make lenses in that range than the ultra-wide or longer telephoto ranges (just compare the prices of various lenses).
The biggest gaps in Pentax's lineup is actually in their primes. Pentax still hasn't (and probably never will) made DA equivalents of the FA 28, 35, 50/1.4, 100 macro, 135, 200 macro, and the 600.
