A C++ library could wrap DOM APIs (WebCC already does this), but achieving a fine-grained reactive model purely in library code involves major trade-offs
A dedicated compiler allows us to trace dependencies between state variables and DOM nodes at compile-time, generating direct imperative update code. To achieve similar ergonomics in a C++ library, you'd effectively have to rely on runtime tracking (like a distinct Signal graph or VDOM), which adds overhead.
