Yes, I suspect that the spindly style does come from these two which
(I guess) have been around for longer...but as you say, the
spindle-factor did seem to get increased.

I would be happy with those names: of course, for letters with some
symmetry (eg N, A, E) two of these names will both be applicable to
the same glyph.  Thus one also needs some precedence rule to get a
canonical name.  {See, I can still apply some of that group theory:-)
