I think the original intention was not so much 28mm exactly, but "twenty-something". I'm going for 28 because I love my macro extension tubes and they demand an FA or earlier lens for best use. My DA21/3.2 would be operating at f/22 all the time, and while this would not be an issue with the actual photography (I'm very fond of tripods and macro rails), focusing precisely at that aperture might present serious issues.
Someone needs to invent a K-mount thingy which goes on the end of a macro tube set and provides stop down aperture control for aperture-ringless lenses - even if it's clickless and doesn't enable you to select an exact figure, being able to focus wide open and then snap shut for the pic would be invaluable (hmm, I think I know a workaround for this, but I'll have to wait until I'm home to try it out).
