Yes, certainly.  This patch is for the ambiguity checker that looks at declarations.  For declarations in modules, this checking might help the programmer of a module guarantee that their clients will never get the per-reference ambiguity error; but a module that gets warnings about ambiguities might have clients that get errors.
