In my case, the next release will forcefully remove language.dat from 
texmf.local, but it wil leave ~/Library/texmf alone.

In general: since language.dat and the cnf files like fmtutil.cnf 
infliuence the availability of formats in texmf.local it is a very bad 
idea to put language.dat and .cnf files in ~/Library/texmf. Formats and 
stuff are system wide and their creation should not differ depending on 
which user runs the configuration commands.

The place to put your modified stuff (and also the place where texconfig 
puts it) is texmf.local. I never change anything in that subtree, unless 
it is really necessary to keep stuff working (nehyph2.tex is a good 

~/Library/texmf is a good place for your personal stuff, but not for the 
stuff that influences formats which are system-wide.

it will use texmf.local, and not be ~/Library/texmf-aware.
