And I'll just fire up a chrome instance which I specifically keep for when my daily driver firefox decides to spazz out and not implement basics in 2026 :'(
How do you make sure that technically illiterate people don't just click away the requestDevice() popup? IMHO a browser offering device level USB access is a security nightmare and there is no way this can ever be made safe and convenient at the same time.
Are you calling WebUSB a basic feature? Because I'm willing to discuss whether we should have it, but that seems like an exaggeration.
