Lua is now in 5.2.0-beta-rc7, which means that 5.2.0 is imminent.
While nothing forces LuaTeX to be based on 5.2.0 rather than 5.1.4,
the diminished locale dependence may be a consideration.  In particular, 
the following change is very significant:

    - Lua identifiers cannot use locale-dependent letters.

I realize this does not answer your question (which I did not quote)
but only Taco and the team can do that.
