They should hire someone from Pentax to design the lenses.

I don't think Pentax design any of their zooms, they are rebadged Tokina's... Except for probably the 20-40mm Ltd that is.

I think I read somewhere, so take with a dose of salt, that the small flange was only really an advantage up to a point with wider lenses, longer lenses beyond 135mm became not only no longer an advantage but made lenses on their own bigger due to making up the extra flange distance.

I can't say I can think of a longer than 135mm lens that is designed for a short registration distance to compare to though. SLRs had long flange and rangefinders short, but usually long FLs were only available on SLRs.
