What's the feature added? That's a semantic game.

Please. It is an operational decision. I personally would be ok with doing away with bugfix-only releases and just releasing a new version with all patches every 6 months. It certainly would make issue management easier. But most people don't want such rapid change, even to the point of resisting fixes to design errors of 20 years ago. On the other hand, most people want their personal fix/feature included right away, in the next release. But if we do not include everything every release, we make decisions as what to include or not.

It is a new feature for the same reason
http://bugs.python.org/issue10730 was. If that had not been added for
3.2.0 (during the beta period, with Georg's permission), it would have
waited for 3.3.s

In http://bugs.python.org/msg124332 from that issue, David Murray refers to "the policy stated in mimetypes". I could not find a policy explicitly stated in the doc, not in a quick review of the code. But I believe what he meant is "Include the most commonly used subset of registered extensions. Add more as requested with every x.y version." If it is really not in the doc, I wish it, or an agreed-on revision, were added. "Add more as requested with every x.y.x release." is the alternative that Sandro seems to have followed.

ISTM, that Issue #10730 was more contentious because it is *not* an
IANA-assigned mime-type, whereas image/vnd.microsoft.icon is and has
been since 2003. Whereas image/svg+xml didn't get approved until earlier
this month, AFAICT.

If we intended to include all registered mimetypes and this happened to be missing, that would be a bug. But there are scads of mimetypes, especially vender-specific vnd types, that we do not include. Many predate 2003 and are probably obsolete, and hence well not included. There might be others that are used generally.
