If it's not copiable then it will fail when used in plpgsql, among
probably other problems. In general there should be no parse
node types that don't have copyObject() and equal() support; and also
outfuncs.c support, for debugging dumps if nothing else. We've been
relatively lax on insisting on readfuncs.c support --- that really only
matters for constructs that can appear in rules.

Ah. I had it backwards: thought it was pulling constraints into the
domain definition from elsewhere.
