Need to drop 3.5 support first.

when is a good time to drop 3.5 support?

[fliiiix]

A good time would have been 3-4 years ago 😅 but we still use it on debian stretch which ships with python3.5 😭

I can check what the timeline is to migrate away from stretch, i assume you would be interested in tackling this issue?

[inquisitev]

Sure I'd take a swing
