For literally every developer on the planet who is not an expert JavaScript developer—or who doesn't wish to be—this is undoubtedly a better development approach. Saying "Remix is the winner" doesn't really move the needle. It's still JavaScript, still React—just with some work pushed to the server instead of the client.
The contract of the web is that while the client-side language in use may not be up to the discretion of the developer (recent evolutions in WASM notwithstanding), the server-side language/framework/OS/etc. can be literally anything which speaks the protocol of HTTP/HTML/etc. JS frameworks for years have repeatedly broken that contract with the claim that we must accept it for…well, "reasons". If it turns out most of those reasons are bupkis—more a matter of preferences than requirements—then we must stop breaking the contract. JS as a server-side language should _get in line_ alongside all the other languages out there.
Why privilege it if we don't need to?
