I'm not sure what you mean by this. Remix and related technologies don't limit what you can do on the client—you still have the full power of React at your fingertips. The difference is that they blur the lines between client and server such that you get more or less seamless server-side rendering in order to populate a web page before you hydrate it client-side with React. If anything, Remix allows you to use React for more use cases where it otherwise would not have been the right tool.
