It's designed to ensure that authors can reliably use a name and expect to
get the same result in any UA that supports that name.
I'm not going to change the spec in a way that conflicts with that -- if
the spec has to change, it'll change either in a compatible way (e.g. to
match what was actually implemented), or in a way that doesn't conflict
(e.g. by changing the name in the spec).

That'll just result in that name becoming the standard.
