- move euenc to collection-latexrecommended
It's tiny, so ok. Also makes sense, in that if fontspec+luatex wants to
read it, it is not xetex only.
By the way, there is no fontspec-luatex package in TeX Live.
But I get the drift.
- make collection-luatex depend on collection-xetex
Certainly not, for many reasons!
