Well, it's done by:
- plain XeTeX & XeLaTeX
- ConTeXt when using XeTeX
- ConTeXt MKIV
I don't know why it would be any more extreme to do it in plain LuaTeX format.

Btw, there is
but it is not used anywhere.

Now imagine user A using both German and French patterns. When he
switches from German to French - should we switch all the German
lccodes for äöü back to undefined? If we don't, there's a chance that
the user will get different hyphenation for French (let's say that the
text contains a name with some German letters) depending on whether he
was typesetting a French-only or mixed language document.
Now imagine user B using some package that deals with Unicode and sets
all the lccodes for the whole Unicode range. If we do change the
lccodes back to undefined when switching from German to French, the
user will have all the letters for the whole Unicode range properly
defined, except for some umlauts which we modified without user's
I simply don't think that changing any codes inside hyphenation files
is the right thing to do. Yes, we can solve many users' problems
(simply hyphenation will work), but create many ugly new ones.
