WB, they're obviously inferior from a technical point of view - but I'm speaking about the visual aspect. There is no open-wheeler with these tyres - it was, for me, something unique to F1. I know others don't like the grooved tyres, but I myself never saw the (visual) appeal of slicks. Saying "they need to go because they're inferior and didn't serve their purpose" should make quite a few parts redundant... Today's mirrors are complete rubbish, for example.
One of my favourite photos of this year's cars is this:
Now, I'm not a big McLaren fan, but it's a stunning picture. And aren't the grooves of the tyres a big part of the composition? I'm not trying to enforce my opinion, but you argued with a technical argument, when the original reasoning was visual..
