I think the dogmatism stems from Google, which delivers this advice as unconditional instruction and often gets parroted, makes the main website grading tool that calls it an error, and says they’ll drive less traffic to you if their grading tool rates you poorly.

Also, I think also led by Google, `font-display: block;` actually behaves the same as swap now, just with a longer wait for the font to load [1]. Iosevka’s webpage does use swap, though.

I was wondering why it did that. This is really the kind of site where this is not a feature you should use.

Funny. Last I heard everyone wanted to specifically prevent the behavior of showing unstyled content before assets are loaded.
