It does if you have a huge screen or feel that all sites' fonts are too small, right? Anyway, every browser I use also persists zoom settings chosen for each site.
On mobile devices as well? Genuinely asking. I keep a battery of custom CSS files for every site I visit just to keep the text settings in sync across OSes, browsers and devices. HN's CSS for example is...quaint I guess but incredibly antiquated.
Here are my settings on Safari iOS, which get added as you change font sizes across sites: https://i.imgur.com/w2lJev4.png. You can see that I clearly agree with you regarding HN :)
