As someone who built his business on django, I'd say I'm super happy with it. However, my biggest gripe with it is it's continued push for updates with breaking changes.

Moving from django 1/python 2.7 was quite painful but possible and now they're suggesting that third party developers stop supporting django 2.2? It was released in April this year!

I know I'm not using any new django features that weren't there in 1.0. I imagine most django users are the same. I'd love to just have a LTS with security updates and conservative non-breaking changes.
