I have. It’s a mix of people saying it’s can only be done with CSS grid semantics and then a few who prove them wrong with flex box. Reinforcing my above question about “why not :after? :last-child? And flex it into shape?”

But I get it. Grids are easy to grok and grid.css is for the birds. Bake it in. Bloat the spec. And allow pixel perfect precision with one (or two) less div.
