It gets easier to make a lens sharp, the slower you make it (to a limit of coarse)
Thus a f/3.5 is almost always sharper and has lower vignetting and distortion than its f/2.8 (or lower) counterparts. If you stop further down anyway, the smart people buy a slow lens to start with!
I think you stress the 'wide enough' issue to far; if people read a 28mm review, a 28mm is what they want! Sometimes a 28mm is to short also you know... ;-)
