This is a thread on the openstack-dev list, but Russell wisely thought we should get broader openstack community input.
Now is the time for opinions. Please be civil, but please express them,
because it will impact the decision in Nova v3 in icehouse.

Subject: [nova] [rfc] drop XML from v3 API entirely

I know we've been here before, but I want to raise this again while
there is still time left in icehouse.
I would like to propose that the Nova v3 API removes the XML payload
entirely. It adds complexity to the Nova code, and it requires
duplicating all our test resources, because we need to do everything
onces for JSON and once for XML. Even worse, the dual payload strategy
that nova employed leaked out to a lot of other projects, so they now
think maintaining 2 payloads is a good thing (which I would argue it is
not).
As we started talking about reducing tempest concurrency in the gate, I
was starting to think a lot about what we could shed that would let us
keep up a high level of testing, but bring our overall time back down.
The fact that Nova provides an extremely wide testing surface makes this
challenging.
I think it would be a much better situation if the Nova API is a single
payload type. The work on the jsonschema validation is also something
where I think we could get to a fully discoverable API, which would be huge.
If we never ship v3 API with XML as stable, we can deprecate it
entirely, and let it die with v2 ( probably a year out ).
