Such a weird take. Of course "self hosting" means "self hosting".
Sure it could be easier/safer to manage, everything can be better.
Over the last couple of years hosting it I had a single issue with an upgrade but that was because I simply ignore the upgrade instructions and YOLOed the docker compose update.
Again, is it perfect? No.
Would I expect a non tech savy user to manage their own instance? Again no.
I like Hotwire but I admit its a bit confusing to get started with and the docs dont help.
Form submits + redirects are a bit weird, you cant really make the server "break out" of a frame during a redirect if the form was submitted from inside a frame (there are workarounds, see https://github.com/hotwired/turbo/issues/257).
