As a gopher dweeb forced to write hackarounds like an external helper to get Firefox into Gopherspace again (either a proxy server: https://addons.mozilla.org/en-US/firefox/addon/overbitewx/ or an actual executable: https://addons.mozilla.org/en-US/firefox/addon/overbitenx/), I'm torn. I would love to see the browser able to speak raw TCP again like I could when XUL/XPCOM extensions were still a thing. But this should really be restricted to browser extensions rather than arbitrary websites because we know someone is going to abuse it, and if we go full Windows Vista as proposed here and ask every connection to be confirmed it will eventually annoy people enough that security will be slackened (and then someone is going to abuse it).
