What value is there in a code point if no two parties are able to
agree on its semantics?  I believe that the conditions for an early
request are:

1. we agree that there is enough demand for whatever it is now and
don't want to wait until the IESG approve a spec
2. we agree that the semantics are stable enough

This might meet the first, but it looks like the second is a little less firm.
