A bit of a skeptical view about your own GPS data accuracy is *always* a
good idea, no doubt about that :-)

Sounds like a good approach. Having something like "You are about to
edit data that is probably more accurate (<Xm) than what you can achieve
with common GPS equipment. Are you really sure you want to change this?"
However, I don't know if the editors will implement something like this
anytime soon ...
