> of all the goods that can happen to the web, 90% of them can't happen due to not having access to font rendering & metrics in JS

I’d be interested to see a representative excerpt of this person’s “goods that can happen to the web”, because it sounds pretty ridiculous to me. Not much needs that stuff, and a lot of that stuff is exposed in JS these days, and a lot of the rest you can work around it without it being ruinous to performance.

It’s also pretty irrelevant here (that is, about HTML-in-Canvas): allowing drawing HTML to canvas doesn’t shift the needle in these areas at all.

100% of my concern about the Web is about privacy and security... and why they don't happen.
