[tex-live] Hyphenation exception files

What is the policy concerning global hyphenation exception files?

The \addlanguage command has an argument for exception files but this 
is empty for all languages defined in "language.def".

As far as I can see, TeX Live provides three exception files:
- dehyphtex.tex (for the old patterns for the old German spelling; this file
   concerns only pdftex, as xetex and luatex use the newer patterns)
- ushyphex.tex (for American English)
- frhyphex.tex (for French)

None of these files seems to be loaded by default, nor with plain TeX, 
nor with
Babel, nor with Polyglossia.

Does it really make sense to provide global exception files and not to load
