Nothing but the desire (at least from my side) to avoid any (even the slightest) 
regression in the changes we're currently making unless necessary.

Currently, the cost of supporting "special" (see below) languages by handling 
them the old way is:
- essentially zero in terms of code complexity,
- winning only 2,2 second when we could win 2.4 in terms of format loading time 
(that is, getting "only" 90% of the maximal win).

Short version: our choice is to use only plain text files for patterns loaded at 
runtime, similar to those found at [1], kindly provided by Mojca. If you want to 
provide such files in dehyph-exptl, then we'll happily support dynamic loading 
of these patterns.

IMO, in the long run, it is the most desirable solution. It is probably the 
format that will be required (or at least recommended) when proper dynamic 
loading will be supported by a babel extension or polyglossia (IMO, AFAICS, etc).

Best,
Manuel.
