I don't think it's overkill for most apps anymore. The performance gains are non-trivial and actually more of a reason these days for me to use SSR than SEO. I guess keeping frontend and backend decoupled is a matter of preference. I don't mind coupling my backend and frontend, and think it's a huge developer productivity gain to colocate components with data fetching. If you already need a server to serve data, I actually think it just makes sense to use that server also to serve html.
