Before Janek implemented shorter stems outside the staff there was a lot of discussion about it, including the effect on flags and avoiding collisions with note heads. You can see much of it here: http://lists.gnu.org/archive/cgi-bin/namazu.cgi?query=flags%2C+beams+and+stem+length&submit=Search%21&idxname=lilypond-devel&max=20&result=normal&sort=date%3Aearly&whence=0 Janek certainly devised new flags. But I can't remember whether the revised flags were actually implemented. Maybe they weren't, as the discussion appears to peter out.
