My own, primary concern about them is having an "experimental" header
become a defacto standard and then having to find a way to get folks

This is my major concern with them as well.
But how often has this even been tried? If there have been *serious*
efforts to attempt this in the past it would be useful if someone could
document in detail the process taken to make the change, and provide an
analysis of why it failed.
