How about this:

Up until now, Xref still had a "still experimental and can change in 
major ... ways" note in its commentary.

I'm going to remove this note (it's indeed getting ridiculous after 5 
years of existence), but how about we remove the contentious binding 
with it?

And then we can treat new bindings more conservatively, with higher 
expectations of stability.

(Resending because the bug tracker rejected it the first time.)
