I should add that none of the resource information symbols are currently (i.e., at the time of writing) used for object linking and only reproduces the prior functionality of resolving module scope resource information. I guess whether these are to be made local or not depends on whether the object linking solution with resource info is going to be immediately bespoke, or will use these symbols directly (either way I expect these symbols to be used, whether directly or through some bespoke resource info linking structure/ABI).
