Require more recent Python version?

I couldn't find requirements on the Python version so I assume we currently only require 3.0?* A lot of important and nice updates happened since then. Would it be possible to raise the requirement to a more recent version like 3.6 or even 3.8? Default versions:

• Ubuntu 20.04 LTE ("focal fossa") has Python 3.8.2, Ubuntu 18.04 LTE ("bionic beaver") still used in the CI has 3.6.x
• Mint 19 has Python 3.6.x., Mint 20 has Python 3.8.2
• Debian 10 ("buster") has 3.7.3, Debian 11 ("bullseye") has 3.9.1
• macOS BigSur has Python 3.8.2

*Actually, in some Dune files f-strings are used for example which already requires Python 3.5.
