Most people today just care if something displays correctly in the major browsers rather than being strictly Standards-compliant nor really understanding why the browser does things the way it does.

They will do when they need tree-shaking performance from the main front end frameworks. There is a very subtle but important distinction between the DOM and the rendered page; being able to separate the two concepts is one of the markers for being a 'professional' front end dev IMHO
