> Users aren't presented with a "barrage" of consent dialogs. There's not even that many of them, and being able to access a serial port is a niche case

It's amazing that you write this and then immediately find the (almost) right answer:

> Unless, of course, the site is malicious/spammy. It's possible to do all kinds of annoying things, from triggering consent dialogs...

And then immediately dismiss that as if that wasn't a valid concern:

> Adding (or not) a consent dialog for webserial doesn't change that.

Yes, yes it changes that. It increases the number of consent dialogs in a system that already has a few of those, and where users are already trained to click "yes" to thousands of annoying popups.

Oh, and these are not just empty words. Recently Mozilla relented and implemented WebMIDI. Guess what: https://x.com/denschub/status/1582730985778556931 It didn't even require a malicious/spammy site. Just regular ad networks.
