Sure. The network protocol is nothing alone, it's just a way for the client to
communicate to the server. My point is that it should be done by the client and
the server, via a network protocol, not by a script running on the client.

There's always going to be some browser that doesn't support any of this. Or
that has a bug that means scripting doesn't run. Or indeed, that has scripting
disabled. Or any number of other weird states. I see nothing special about the
browser here as compared to script based on browser APIs.

Modern browsers update continuously in a matter of weeks these days. It's just
as possible for a browser to improve faster than a site updates its code than
the other way around. In fact, since there are fewer browsers, it's more likely
that they'll be updated.
