Even the softest, most specialised road tyres are light years away from those used in F1.

That's certainly true. I don't see a benefit either on the road. Today's sportcars are already fast enough.
In F1 it's all about understanding the tires and keep them in their optimal window. I only see a benefit in F1 and we'll see how big it is. The advantage is having a lower aero restriction and a warmed up tire already at the entry of a turn.
