completly different route than the current approach anyway.
Ok. We'll have to make a (possibly temporary) decision for them: if we don't
support loading them from LuaTeX atm, we need to provide at least a sensible
error message.
Oh, please don't care about the timestamped patterns. The time stamp is
only a crude hack to avoid file name confusion while testing patterns
that are under development. We are happily waiting for Polyglossia to
provide a way for ageing patterns some day.
The patterns in the dehyph-exptl package were originally meant for LaTeX
and Babel only. Mojca just grabbed our patterns for XeTeX (for
converting the ugly conventional German OT1/T1 patterns to UTF-8 seemed
hard), arguing that there's no need for (self-)backwards compatibility
as long as XeTeX's version number is lower than 1.0. So, as long as the
latter holds, there is no need to consider timestamped patterns in
hyph-utf8. But once XeTeX or LuaTeX grow v1.0, it would be nice to have
an official solution for ageing patterns in TeX. Freezing patterns is
bad, IMHO.
