This seems rather restrictive. It would mean that if we found a bug in
sphinx-0.5 that was fixed later in sphinx development we couldn't
depend on the bug being fixed for the lifetime of Python 2.6, to
satisfy this requirement. Ditto for new sphinx features that might
make life easier for the doc authors, or in some cases enable new
types of markup that would clarify the docs. It would make backporting
doc-fixes from 2.7 harder too.

I could live with "only depend on released versions of anything" but I
don't think I could live with "don't depend on anything released after
2.6.0 was released" (which IIUC is what you are proposing here).
