thanks for the explanation.

I’ve written up my understanding of this, along with a potential use case (for design system components)[1]. It doesn’t feel like a niche case to me however perhaps it is in practice or this is enough of a step forward to get round the downsides and still be shippable.

If this is where the spec goes I would also like to see options left open for a return of the single dimension subgrid in a future level (as Rego mentioned).
