file=xxx.tex is written into language.dat / language.def and used by
(Xe)LaTeX and plain (Xe)TeX. LuaTeX uses the files mentioned in

No, dehyph-exptl.tlpsrc:

depend hyphen-base
depend hyph-utf8
execute AddHyphen \

 lefthyphenmin=2 righthyphenmin=2 \
 file=dehypht-x-2009-06-19.tex \
 file_patterns=hyph-de-1901.pat.txt file_exceptions=hyph-de-1901.hyp.txt

Manuel did the changes. I have no idea if it's documented anywhere
else, but some simple doc is here:

See http://tug.org/svn/texlive?view=revision&revision=18612 and related commits.
