There are to be sure, features of Unicode that are "embarassing", but I don't
think this is one of them. Take another case: even if consistent practice in
Poland is to have the grave accent in ó at a different angle than what is
practice in France, that does not make it a mistake for us to have encoded both
as ó. These sorts of preferences can be taken into account in the tailoring of
fonts to particular practices, and this issue doesn't not require that we let a
thousand middle dots bloom.
And canonical equivalence was the mechanism for saying that two variants of
character really should never have been encoded (but we had to for compatibility
reasons).
