The most important part of this is toward the end, and whether you consider it a limitation or a feature is a matter of perspective: the modern commercial web does not play nice with this. So static HTML and blogs yes, Reddit and most anything commercial no.

You can actually get other close-to-browser experiences with stuff like xwidget and embedded WebKit (https://emacsdocs.org/docs/emacs/Embedded-WebKit-Widgets) but generally it’s not worth the fight for commercial sites these days; everything is vibed and only tested against Chrome, so if you’re lucky they’ll load in other Chromium browsers and _maybe_ Firefox.
