I think it's fine not to release before you're back, I see no hurry there, and
you probably don't want to revisit the whole build process now.

Good news.

Sounds like the best solution to me, both for maintenance and for the user.
Thanks for making that move.

I concur with Ulrike: it would be even greater to (re-)load xunicode at the
right moment in fontspec if it has been loaded before. I guess you can force
reloading by \relax-ing \csname ver at xunicode.sty\endcsname.
