Whether it is dropped is an open issue the working group should resolve,
but yes, that is my interpretation.

The difference, if there is to be any, would be coming from URI being
a token on its own, unlike other functional notations.

I think 'font-family' still allows pretty much any value unquoted, but
I am not sure which font-family 'font-family: [' would select; perhaps
if you install a font '[' and a font '[]' and either is selected... We
might want to make a special -w3c-anything property for this.
