Sorry for being so imprecise. What I wanted to say is: once we have utf-8
patterns, we still need a bit more information for LuaTeX, in order to choose
between loading them statically (in the format) or dynamically. So, we still
don't get orthogonality.

The more orthogonal solution I can think of right now is:

1. Static vs dynamic: static is for non-luatex engines, or with luatex, for
languages without an entry in language.dat.lua.

If we're in the dynamic world, it's luatex hence utf-8, period.

In the static case, the engine can be any of pdftex, xetex, luatex. Here the
relevant question is: 8-bit or utf-8? And this question is best answered in the
loadhyph-XX.tex file that with cutom language.{dat,def} files for xetex ad/or
luatex, IMO.
