I'm operating from the principle that there should not be a special
syntax that only applies to dependency on the version of Python.

The same syntax used for specifying any dependency on any package should
also be sufficient for specifying a dependency on Python itself. That
being so, the cost in complexity of having a special dependency syntax
just for the version of Python should weigh strongly against introducing
one.
