In both cases (200 Content-Location + ETag / 201 Location + ETag) & it
does, and both are subject to the same security implications that it's
not always safe to assume the response is authorative for the indicated

The two is really just two facets of the same concept of indicating that
the action was taken/resulter in a resorce at a different location than
the request-URI, with the main difference being the meaning of the

with a resource is a lot more dangerous than associating just a wrong
