I'd notice things work out much more cleanly with fontspec loaded.
However, I'm working on stuff for a macro package, where I can't be sure
that xetex users will definitely have fontspec loaded (they probably
should, but that is a different matter).  However, the point remains
that, for example, Å should appear as \AA, which works fine without
fontspec.  Perhaps I'm expecting too much from xetex at the moment,
especially in maths mode.  As a package author, I do my best to think of
as many awkward questions for myself as I can, so that users don't!
