I think that may be the million dollar question. I don't know. The bike I have, the Bianchi Volpe has a decent stack of spacers under the stem, so I don't have a problem. I would say if a bunch of folks start complaining about the lack of adjustability, they might do something. I would rather have a stack of spacers and a -17 stem than no spacers and a + 5 stem. The one problem is the number of people who think it looks 'uncool' to have spacers under your stem. Oh, well.

God bless!
