> even go super old-school and run a web server at home. It's not as if we're short on options in 2020.

Though it's old school, it's incredibly difficult to run server at home now at least in India. The network I connect to is behind a NAT which is behind another NAT. At least that's what I saw when I tried to host my blog on Raspberry PI at home over a year ago. Ultimately I gave up on that endeavor. If anyone has solution that doesn't involve third party, please suggest.

I think I will have to wait until my ISP implements IPv6. That could take another decade :/

You can always use https://ngrok.com and other similar "tunneling" solutions. It works like a charm:
