It's impossible to submit a <select> element (without a size="" attribute
or multiple="" attribute) without it having a value -- essentially,
required="" is already implied.

That seems like an invalid use of <option> to me. It would be better as:
<label> Choose an option: <select> ... </select> </label>

True, required="" would be useful in this scenario.

This will still work without required="". :-)
The reason <select> isn't able to use required="" currently is still the
same as the reason when this came up in November, as Jon cites here:

...namely, we're still waiting for browsers to implement the current crop
of new additions to forms, and adding more will just make them have a more
buggy set of implementations. This feature is in the spec marked as a "v2"
feature to add at some future point.

Currently you can do this just by not providing empty values and not using
multiple="" or size="".
