People have been dragging their feet on subgrid, masonry, etc for almost a decade. I followed it pretty closely for years but stopped when it started turning into a Christopher Guest mockumentary.
Masonry or grid-lanes, who cares? I’m just glad masonry (the feature, Baseline 20XX) and subgrid (Baseline 2023) are finally here.
