Yes, web view and standard library are being used in the same sentence. How on earth a web view might be considered for inclusion in a standard library is beyond me.
In-context, this makes a bit more sense, though I'm not sure I'd vote for this proposal if I were on the committee. The introduction does a decent job of explaining the motivation; this is an alternate to the long-going discussion about putting 2D graphics in the standard.
Getting outraged at proposals, especially from the outside, doesn't make for a healthy process; not every proposal becomes accepted. Off-the-wall proposals can sometimes help explore a problem space with a new outlook. That doesn't mean that every single proposal is worth taking equally seriously, but Hal is a well-known name in this space, and has done a lot of good work.
(Incidentally, this kind of situation is why we're interested in adding stages to Rust's process; we want clarity around the maturity of a proposal. Some proposals are just for brainstorming. Some are more mature. It can be hard to tell sometimes from the outside which is which.)
