An ABI break for that environment would not be the end of the world, especially considering those environments cannot afford the code size from locale support. AFAIK, @abidh is still maintaining that work, and would be able to give a definitive answer.

My last work on this stuff was before that assert was added so never faced this problem. But I agree with above comment.  We could live with such ABI breakage.
