If a browser has too many compatibility issues, users will switch away. Outreach to the sites in question takes time and is often unsuccessful. Quirks is the pragmatic answer.

WebKit is used by the second most popular browser after Chrome. Don't forget iOS users.

My iOS/Safari is so bad, I have both Firefox and Chrome installed as a backup in case it doesn't work. They should start fixing Safari for real instead of adding Quirks.

That's an odd way of saying the third most popular browser.

I don't know about quirks specifically, but often it takes many, many months before a WebKit commit actually ships to end users in Safari.

Anyway, Apple engineers aren't known for their outreach.
