"Dry stack" is another term for that, a stone wall without mortar.

In my opinion, thinking of this as a grid is misguided. It's barely different than flex columns. I would want to be able to have some objects take up more width than one column, or not have clean columns at all. Like "space filling" and "mosaic".

I don't think of dry stone walls as masonry myself. I actually think that's the distinction between masonry and not-masonry!

But anyway, I think the second last section on the link, the part that addresses the wrongness of the name, would align with your opinion.
