Well, but... if the various OSes are sharing the same naming attribute, it seems
like there's an unbreakable chain of connections between them. Either the
attribute is case-sensitive, in which case the natively-case-insensitive OS will
be confused, or the attribute is case-insensitive, in which case the
natively-case-sensitive OS will be confused.
The way that I look at it is not that the directory is serving the OSes, but that
the directory is defining a world that the OSes are choosing to play in... and
when they choose to play in the directory's world, they have to live by its rules.

It's tempting to suggest that a single entry could have one name attribute that's
case-sensitive and another that's case-insensitive (presumably from different
auxiliary classes), and technically that'd be possible, but seems like an
administrative nightmare... a very high cost to pay for the 0.1% of names where
case-sensitivity is important.
