display:table was never really evangelized for tabular layout. They were pretty much ignored and the literature and documentation missed the point. Tabular layout is really just another word for grid layouts. Grid layouts took forever to arrive. Tables were the only reliable way lay things out in a grid for a very long time and yet were discouraged regardless. There were people who knew about display:table and used it and some of us were nevertheless told we were doing it wrong because people got hung up on the word table.

Like many things in CSS features that should have been present in the original 2.0, when it became clear that the web wanted to be laid out like a magazine, Took multiple decades to actually appear. As a result we are still seeing the fallout of those failures in our ecosystem.

Sorry are you saying ‘display:table’ was not viable for grid-like layouts because someone might confuse it with the html <table> tag?

That is like saying Go is not a viable programming language because someone might confuse it with GOTO and consider it harmful.

I'm saying that CSS has always had really confusing messaging around what is considered good practice and what is considered bad. If CSS had actually had the equivalent of Go's stdlib and documentation with well established good practices that were pragmatic we would be having a very different conversation right now.
