Nah - I've only had down tube and STI equipped bikes, but I've seen what just hitting the regular end of the bar (and what hitting a handlebar that the end has fallen out of - not me thankfully - NEVER ride with out plugs in place!) can do to a person's leg... my imagination thinks about what something sticking out even further and possibly being pointy might do. At least the pointy end of the shifter is mobile, so the possibility of really skewering yourself would probably be remote??
