Norbert, No worries for cherrypy3 py2 revival.
Though I still have a concern that you wrote your plan is to get Calibre to use Py2 for how long as possible. IMO that shouldn't be the plan. Your plan should be to try to fix the situation as early as possible, rather than as late as possible. I know it may be difficult to forecast, but do you think you could get a reasonable timeline for the Py2 removal in Calibre? Cheers, Thomas Goirand (zigo) P.S: Sorry for breaking the thread (ie: in-reply headers), as I can't find your message in my thunderbird...
