> Do you know that Chrome argued that <dialog> should be removed from the platform because it's a bad API with multiple issues?

That's not at all what the comment you linked to says. It says there was an open question about if <dialog> should be removed from the spec because interest hadn't materialized from Firefox and Webkit for the element after four years (and wouldn't for another two years after that).

What I'm saying is that the goal of standards and cross-platform support across time is valuable. The "open web" is a good thing for humanity.

Work towards this goal is a huge shit show. And messy. But it's a good goal.

The flavor-of-the-month frontend insanity is not serving this "good thing for humanity" goal as I call it. It's all well-intentioned and I'm not looking a gift horse in the mouth. But it is different.
