I am totally not a friend of anyone still using py2.x (esp. as it has EOLed [1].

Non the less one doesn't need to use log analysis and py2.X if you want to use Matomo as a GA replacement in the frontend.

So yeah - they should fix the log analysis part with py2 -> py3. But that doesn't invalidate the whole tool imho.
