Python version for opentf-tools very recent

Hello,

I want to use opentf-tools in our projects to launch workflows. The problem comes from the very recent version of Python requested for the installation of opentf-tools. We are using Ubuntu version 18.04 which offers in the official repo version 3.6 of Python while we need version 3.8 for opentf-tools. This forces us to use a version not present in the packages.

Moreover our Python programs use some packages whose versions are incompatible with the installation of opentf-tools.

Wouldn't it be better to also offer a "standalone" version created with PyInstaller for example ? This should solve the compatibility problem.
