Off topic - pip-compile and dependabot
Min introduced the strategy to use a requirements.in file to build requirements.txt using pip-compile (made available by pip install pip-tools) in z2jh, and it has been a great experience. We also have dependabot automatically submitting PRs with various updates as configured like this.

Thanks @consideRatio! dependabot is really a good idea.

I will setup it after I figure out how to get rid of the aiohttp version pin :(
