Re: [csswg-drafts] [css-nesting-1] Can we relax the syntax further? (#7961)

> How difficult/expensive would it be to _change it_ to do so?

The best numbers I have is that it would cost us about 2% of total page load time (not just parse time; all of load time), since we'd need to remove some optimizations that have been said to yield approximately that.

I don't share this goal; I would like us to just get the syntax (_any_ syntax) specified, out the door and be done with it. So no, I won't be spending resources trying to bend our minds around how we tokenize CSS to this avail; I can NAK what is a non-starter for us, and that's what you'll get.
