Comment 9 for bug 1538620

Scott, yes, my comment was not about needing to fix it with a microversion or how it fails with M-Nova and L-Cinder. It was as you said where it is unlikely anyone would be calling it (in Mitaka) with both arguments. And if they did, that they would expect a failure.

So my comment was - granted it is a behavior change in an existing API - but do we need to revert it to the old behavior since no one will call it expecting the old behavior.

As long as the v3 API has existed, it has allowed both to be passed in. Let's just keep it that way and Nova can expect that with the base v3. No need to bump up a microversion to remove and then readd a change.
