       @firefoxwebdevs so Web Serial is OK but WebHID and WebUSB are not?

       @hj what do you mean by 'ok' here?

       @hj Web Serial is the second API we've applied this new permission flow to, the other being WebMIDI. We'll continue to look at other APIs on an individual basis.

       @firefoxwebdevs I hope you implement at least WebHID because it's very popular and lack of support for it in Firefox just drives popularity of Electron and Chromium(-based browsers)

       @hj which sites do you use that use it, or what are your use-cases for it as a developer?

       @firefoxwebdevs something like https://usevia.app/ https://launcher.keychron.com/ Same idea as Web Serial, just different hardware API. Usecase is the same - controlling and configuring hardware.VIA and Keychron Launcher let me configure my keyboard and mouse without having to download a windows-only "driver" and run it on wine with terrible results.
