Python 3.6 is also EOL; will we drop that soon?

[Ousret]

I do not know for sure at the moment.
To be considered; some of our primary integrators like aiohttp still support it. And as far as I am aware, there is nothing in the code of this tiny library dedicated to python 3.6.
If we drop it, it would be as simple as patching the version requirement.

I am more inclined to keep the support while it does not create specific code or patchwork to make it work.
The probable outcome of this would be seen in the next major.

Hope that answers the question.

Got it, thanks! When you do I'd like to open a PR switching to PEP 621 project metadata 🙂
