Currently I have a huge dilemma:

• backport all my code to TF 1, in order to use Stable Baselines and my code in one project
• or use something less mature than Stable Baselines (eg TF Agents) only because I have Tensorflow 2.3 code in my project

Couldn't you support also newer TF versions (tensorflow>=1.8.0,<2.0.0 could become tensorflow>=1.8.0).
