as far as i (quickly) read that list i've never found that.
At that time the French patterns file is independant of any font
encoding widely used to typeset French documents. Do i missed
something?

One point can differ from, let's say, T1 vs OT1 is the hyphenation
char. That's the reason why Bernd Raichle designed hypht1.tex.
To easily include this file at initex i modified few time ago the
loading mechanism used in French Pro to accept the font encoding as a
suplementary argument in language.dat file. Defaultly this is t1
and hyph<encoding>.tex is loaded if it exists. To avoid loading
a "-" should be provided.
