Yeah, Chromium's implementation is IMO very elegant and genuinely improves security for most people. That's why I'm a little miffed by comments that paint it as an obviously terrible feature, just like happens with the "read/write to a specific local folder" API.

These days, new browser features often aren't in the users best interest, I understand and share the commonly discussed concerns on those. But compared to the alternatives, these specific APIs genuinely improve safety for most users AND make things more accessible for newbies and pros alike. Blocking them on principle (& without specific technical concerns) will not protect users when their remaining option gives malicious actors far more access without any exploits!
