From what I understand it's the motivation for the 209 response code in
PATCH, allowing the client to request the patched resource so that it
can verify that the patch was applied like expected.

If the client can not trust that the 209 response to PATCH is infact the
resource after applying the patch then there is not much point in
supporting 209 for PATCH, and it can just as well be specified that the
client should GET the resource if it needs to verify..

Henrik
