The simple case is a case srcset (the DPR parts) solves and I'd argue should be
used here instead.

Sure you can use ids. But the idea behind the CSS proposal was to allow better
sharing of the breakpoint media queries. Using ids doesn't share, using a class
would. Src-N you have no choice but to repeat everything everywhere.

They look better in an editor. CSS is syntax highlighted. Src-N's format isn't
and likely would never be — as most HTML attributes aren't.
