I'm hoping that Python won't have any issues building and running on 10.6, but I don't have it yet so I can't personally test it out. How would you quantify "works well"? Do you have any thoughts on tests you'd run other than the standard test suite? If 2.6.3 is shown to pass its test suite on 10.5.x, is that good enough? Are the specific bug fixes necessary for 10.6?

To follow-up, I've now run the usual "standard" OS X installer builds and regression tests using 2.6.3rc1 plus a few additional tests (IDLE and package installation) and have found no regressions from 2.6.2 and verified that some release-blocker problems have indeed been fixed. In particular, Issue6957 regarding extensions module building on OS X 10.6 is fixed as discussed in the issue.

The tests involved the target python.org installer configuration:

plus the following additional configurations:

plus, a quick check of the currently unsupported configuration, with no new regressions noted:

As noted in various tracker issues, there are still a few unresolved issues with universal builds built on 10.6 (e.g. 32-bit vs 64-bit selection, IDLE with Tk 8.5) which is why this last installer build configuration is currently unsupported.

In my opinion, the standard python.org OS X installer for 2.6.3 now "works well" on 10.4, 10.5, and 10.6 and is ready for release.
