Not implementing generic-flet and friends is not really an option for most
implementations without action from X3J13, and some members of the committee
(specifically rpg) have stated a strong desire to keep them in.
SPECIALIZER-DIRECT-METHODS was included in a list of names proposed as being
part of a `defacto standard'. Including an unessential and very hard to
implement feature in such a proposal is not likely to encourage it along the
way towards general acceptance. If the generic-flet excluded semantics were
adopted, applications which depended on the complete list semantics would fail,
so it seems like a good idea to decide what is going on here early, before
anyone has a chance to write themselves into a hole.
