Yes, all constant strings which appear in script are interned. But again, we made change that expressions consisting of just strings (which covers docstrings) are discarded. Submitting a bug for this issue will make sure it's revisited and not forgotten.
Before I submit any more bugs I should probably learn to build the project and flash the board and all that good stuff - it probably is fixed as you say, but I'm still running the version of micropython that came on my board and I haven't tried the unix version or anything.

I flashed my board and it looks like that issue with the docstrings is at least partially resolved - space is allocated for them on import, but the garbage collector removes them when it runs. Seems adequate to me? I will log a bug if you disagree.

Hmm, I'd guess parser could free such strings explicitly, saving gc from extra work, so I'd suggest filing a bug.

This means that we should include docstrings in micropython modules, right?

You can, and you should not be concerned that they may waste memory when run on MicroPython (they won't).
