Off course it makes sense! On your second paragraph there is something I am pushing towards on my bikes: Longer chainstays. If the bike has a super short chainstay and a super long reach, It demands a kamikaze way of riding. If the bike is balanced, long reach with long chainstays, you are centered and don't need to kamikaze your way downhill. That alone for me is a vital morale boost. Hip angle won't be a problem as soon as shorter cranks get available. This will get on more and more bikes very soon.
