Sorry for the surprise! The justification (FWIW) would be that the  
assignments there are derived from the Unicode character database, so  
I think it's reasonable to provide these as a default starting-point.

This is definitely true; I should have done that from the beginning.

Will: I think a version of your \newcharclass (or perhaps  
\newXeTeXcharclass is better) macro should go into the format itself.  
We could put it in unicode-letters.tex, I suppose, but that's  
essentially a data file, so probably best to have it in a new little  
file that can be loaded from xetex.ini and xelatex.ini before reading
