Re: [csswg-drafts] [css-nesting] Problem with mixing properties and selectors (#8249)

>  starting a declaration with a symbol is already very likely off the table, given the prevalence of people using a random ascii symbol to "comment out" a property.

I'm not convinced by this, because 1) I don't see this statement backed by any data, and 2) a declaration preceded by a random symbol may stay as invalid even if we add a new feature that uses that same symbol.

Like, even if there is plenty of `+width: 10px` on the wild, we might be able to add a new future that does something special for e.g. `+width+: 10px`. Option 3 without lookahead closes that door.
