Hey,

I don't like Browsers to go CISC way. Simpler -> finer ?

Why?

Any feature that we add up indeed cause some extra CPU cycle. I am not a believer that we need an extra regex like this.

Of course, the overhead caused by this is minimal, so is the benefit. Also very tiny percent of web apps will use this anyways.

It could make the shipped css/js to some extent.

Overal I don't like this tradeoff. I dont want web to have more fanout
