I think it's the issues in "Go plus a few simple libraries". Frameworks come with all the extra features built in. If I need rate limiting, I can just open rate limiting docs and add it to my route, there is no need to search some library or blog post on the "best way" to implement rate limiting middleware in go.
I run a web client for my app https://github.com/karlomikus/vue-salt-rim and I'm using some PWA features. It's mostly just to get the native app feeling since I don't want to maintain separate apps for all the platforms.
