Something that uses less RAM would be nice. Other than that and the spyware from Capital-G Google Chrome and Capital-M Mozilla Firefox, I don't have a problem with it being sparse. It's millions of hours of de-duplicated work.
I'd like an alternative to HTML though. If I was to make a browser maybe I'd focus on replacing HTML because I can't stand it, and replacing js just because the runtime is heavy.
Like, a browser that only runs wasm and has nearly no JS runtime would make me giggle
For less RAM, try: Dillo, Netsurf, Otter Browser, K-Meleon, Pale Moon, Basilisk, Ultralight.
As an alternative for HTML, why not QML with Canonic browser?

That's not a browser.
More or less by definition, a browser is an application that can use HTTP (and potentially other protocols) to make requests to other systems and retrieve stuff described using HTML (and possibly other formats).
Sure, a tool that just loads wasm and executes it would be fun (and probably exists, at least for the local case). But it's not a web browser.
As opposed to current browsers that run wasm and JS I mean
Yes there would be a DOM in addition
