What was the specific Python 3 issue? I didn't see anything in your post specifically about Python 3.

As far as I know there is no planned support for Python 3 in the standard env. I've been using GAE since 2010 but I'm a little uncomfortable continuing to writing new apps in Python 2.7 when they have a clear end of life date set now.
Given it might take you guys a year or two to support 3 after you decide to do it, then a year or two for me to port my apps over to python 3, my apps might be running for a while past the end of life date for Python 2.7.
Besides, I can't just keep writing 2.7 apps forever, so either I you guys have to update the SE to 3, or I need to start evaluating and comparing the flexible environment to what everybody else offers.
