This is slightly incorrect (though irrelevant to the issue here). The
default xelatex format does actually use hyphen.cfg from Babel.
Polyglossia provides indeed hyphen_cfg (a stripped-down version of
babel's hyphen.cfg) but it is only loaded if you rename it to hyphen.cfg
and then recreate the xelatex format. See the polyglossia manual on p.
6, n. 3. Eventually I may indeed rename it to hyphen.cfg, but I have not
experimented enough with it to decide whether this would be a good idea
or not.
