Well, formerly you would have been right, but WebUSB and whatnot are gaining a lot more traction.

I didn't take WebUSB seriously until I steered someone to flashing a small firmware onto something and they could do it straight from the browser! And it was a nice workflow too, just a few button and a permission click.

Two other examples I can think of are flashing Via (keyboard) firmware and Poweramp using WebADB via WebUSB to make gaining certain permissions very easy for the layman. I imagine it's gonna get more and more user in enterprise too.

Firefox is seriously behind by refusing to implement it.
