Would be good to get something about "advertised as supported" in there.
The use of Allow is for servers to advertise that they do support a
given method (or indirectly HTTP extension) so clients MAY enable the
use of those methods, not to tell clients not to use certain methods.

I am fine with that with the above clarification of the use of Allow
keeping it on track with the intended use.

If not clarified I am afraid that implementers may loose sight on why
Allow should include a meaningful list of methods or why they should
send Allow at all.
