Would it be possible to publish the asyncio python client found at https://github.com/facebook/watchman/blob/376b9aeab18d75287f7f100313093f99d0b7a82a/watchman/python/pywatchman_aio/BUCK to Pypi?
Seems like the only way to use it atm is via git submodules and it seems to have a generally more friendly user interface than the sync one.
