Yes, I saw that listed in P&L, but haven't been concerned since I've never
personally encountered it in literature, or had users request it (unlike
the barred b).

OK, I wondered if that might have been the case. (If only there were some
way such decisions could be documented in the book... )

As I was suspecting.

Well, only that it would make it easier for us to avoid proliferation of
fonts while also providing fonts that our users can use with current
software that does not yet provide means of selecting glyph alternates.
But, I've been vocal about not encoding presentation forms more than once
on this list, so I guess I need to swallow the same medicine I dish out.
