The problem that this doesn't cover is the care where two patches are
applied in rapid succession. Returning the result allow a client that
cares to compare the result with expectation to apply that level of
verification. The validator will not match when the first client makes its
request since the second client has already 'upgraded' the current
validator for the resource leaving the first belt and suspenders client
w/o an easy way to confirm correct application of the patch.
