I see.

But there's no way to meet it that doesn't involve lots of busy work?

Draft formatting is plenty of work already. All I'm trying to do here is 
make people who are interested in knowing what "pingback" means be able to 
find out, and make people who might be tempted to use that name aware of 
the existence of the keyword's existing use. Having to republish an eight 
year old spec seems like a lot of overhead.

True, but presumably that's actually a good thing -- it means that if 
reality changes, and the spec is updated accordingly, the registration 
will still track it. It would seem that preventing changes is a bug, not a 
feature. (The spec is only currently frozen because Stuart and I don't 
think it needs changing at the moment and don't want to ramp up the 
process of changing it.)

I don't think there's any risk of the pingback spec's state becoming 
ambiguous. If hixie.ch goes down, and people still care about the spec, 
someone can put up a copy elsewhere and update the registration. That 
doesn't seem like a problem of any practical importance.
