I'm not sure that I understand how this is supposed to be done.

There are all kinds of problems connected with that:
- Most important: How should the system know when language.dat needs
to be regenerated? Which script would generate that and what should
MikTeX do?
- What should happen in MikTeX which has a gui to choose languages;
and then someone edits language.dat.lua, possibly making some typos?
How can MikTeX know that it needs to modify the configuration once
somebody touches language.dat.lua? [let's forget for a moment that
luatex is not out yet]
- language.dat.lua could contain a large number of languages and
patterns that are not even compatible with pdfTeX (one could control
that with an additional option of course).
- Which problem would you solve/simplify with that?

Before that simply all the patterns have been loaded. Is that a better option?

The only alternative approach that I see would be if we would ship the
same information as tlpsrc files in somewhere in hyph-utf8 and then
tlmgr would read that file before executing AddHyphen directive; that
way it wouldn't need to know the information about specific files in
advance (but it would add quite some complexity).

MikTeX has a gui for selecting languages. Honestly, I have no idea how
it works when we add a language or when we modify something (but
language names are supposed to be more or less stable).
