Server side rendering has been with us since the beginning, and it still works great.
Client side page manipulation has its place in the world, but there's nothing wrong with the server sending page fragments, especially when you can work with a nice tech stack on the backend to generate it.
Sure. The problem with some frameworks is that they attached server events to things that should be handled on the front-end without a roundtrip.
For instance, I've seen pages with a server-linked HTML button that would open a details panel. That button should open the panel without resorting to sending the event and waiting for a response from the server, unless there is a very, very specific reason for it.
