There's still no framework in e.g. Go that comes anywhere close to matching Django. It's pragmatic, doesn't do too much meta-magic (I still don't "get" Rails), lets you strip away any layers you don't need, etc.
But the remaining 20%? Now you've dug yourself a hole with no recourse but a complete rewrite. It's time/money you would've otherwise spent anyway, but that sunken cost fallacy hits hard.
One framework which does not have this problem - or at least minimises the problem, is the Yii framework for PHP. A very nice and underrated framework
I don't think Go is an apt comparison. Its philosophy is to eschew traditional frameworks in favor of relying on the rich standard library as much as possible, and on small external libraries when needed. This does lead to a duplication of effort and bespoke mini-frameworks that only technically have a fraction of the features of a typical framework, but the end result is much simpler, more understandable and flexible. All in a highly performant language with a great ecosystem, packaging, and tooling <3
That said, Django is an amazing framework that has stood the test of time. Like many here, it was one of the projects that kickstarted my web development career. Kudos to the team and community, and here's to another 20! \o/
