Did you check whether layouts break with the default font?

We should also make sure to match the fallback font to the current font as much as possible.

None of the pages I looked at have breaking changes. Would it be worth doing something like Percy for this?

do you mean match the spacing/weight or the declared font (or both)? I am not sure how much tweaking you are interested in having done

Separately, we do not seem to be preloading or prefetching the fonts on the at any place in the repo, from what I can grep. Should that be added?

Percy seems like overkill. It'd just be nice to have the fonts roughly matched. I've created #5335 to fallback to the system font instead. That works good enough in my opinion.

You're right, we're not preloading the fonts. I'd sworn that I've added this back in the day. I'm not sure whether we should add it or not. It might block bandwidth on poor connections.

I didn't think that a font prefetch that is optional would block, but that makes sense

Is prefetch needed in case of font-display optional? I thought the browser will download the font anyway.

sorry, no, thats not what I meant. Rather, I meant if you prefetch an optional font, I did not think it would ever block a connection.

Created #5336 to track font matching.

@sebastianbenz, no worries, your memory is working fine. We've had preload statements for the fonts and removed them midst September which according to Kevin had a positive effect: #4533 (comment).
