<div style="font-family:'courier new',monospace;font-size:x-small"><br></div><div style="font-family:'courier new',monospace;font-size:x-small">1. Replace existing WSGI framework in the existing API versions</div>
<div style="font-family:'courier new',monospace;font-size:x-small"><br></div><div style="font-family:'courier new',monospace;font-size:x-small">In my opinion there's a bit of risk here with changing the entire framework tha the API is built on, and even though I'm confident this can be done I'm not sure of the return on the investment and really I don't see anything that compelling when you consider all of the changes in not only the API code but in the unit tests that would be affected.</div>
<div style="font-family:'courier new',monospace;font-size:x-small"><br></div><div style="font-family:'courier new',monospace;font-size:x-small">2. Bump to a new API version and isolate the changes to that new version</div>
<div style="font-family:'courier new',monospace;font-size:x-small"><br></div><div style="font-family:'courier new',monospace;font-size:x-small">This is my preference and IMO the right way to go, however there's no driving need for another API version bump in Cinder currently. I personally don't like the idea of bumping the API version for every release, even if we're keeping things stable and maintaining backward compatibility without issues. For me there isn't an overly compelling reason to justify this change for the H release.</div>
<div style="font-family:'courier new',monospace;font-size:x-small"><br></div><div style="font-family:'courier new',monospace;font-size:x-small">My plan is to go with option #2, and to push this change out until the I release.
