I felt that this was quite unnecessary because of the limited scope of
the patch, and because this raises thorny issues of both semantics and
implementation. Tom agreed with this general view - after all, this
patch exists for the express purpose of having a well-principled way
of obtaining the various fields across lc_messages settings. So I
don't see that we have to do anything about making a constraint_schema
available.
