I love Safari as much as the next person, which is to say not much. 😝
I’m being facetious, but I have two complaints:
1) It’s the oddball when it comes to developing extensions for it because it requires a corresponding app. Pretty annoying.
2) It deletes a site’s data storage after 7 days without visiting. I get why I think (anti-ad/privacy) but there’s a privacy hit—otherwise private local web apps will lose data unless they provide a mechanism for storing it remotely.
