There is no "prohibition" of course and as we all know RFCs are not
jail sentences.  In the abstract is says very plainly that embedding
globally-routable IP addresses into Internet hosts is discouraged.  And
if you look through the doc you see the word "should" where you might
have thought "must" was.

I think the 4085 provides generally good advice and I think it has
something to say in this case.  It doesn't necessarily prohibit this
behavior, but I think it does suggest against it.

Personally I don't know if after wide deployment the end result would
be bad or good.  I could envision both scenarios, either certainly seems
very plausbile with a little bit of luck in one direction or the other.

I would probably be much more pessimistic if this change was going
into default configs of something like CPE devices.
