At some point the countries with the least developed infrastructure eventually go through some government-led project to improve infrastructure, and that makes them leapfrog most other countries just because all their infrastructure is suddenly new. It happened in South Korea 15 years ago, and it’s happening in many African countries now. I don’t think we should burden a security protocol with a problematic mode based on a perceived need that might evaporate in a couple of years. Deploying high bandwidth is even faster now that you can make the last mile wireless rather than running copper or fiber to individual homes. > In the rural US, I understand low bandwidth is the norm.

Also see > https://www.google.com/search?q=rural+us+high+speed+internet. That supports my point. To quote one of the top results from that search (the first one that was not an ad): "53 percent of rural Americans have no access to high-speed Internet, which he defined as capable of downloading content at 25 megabits per second.” 15 years ago, having “no access to high-speed Internet” meant having just 56Kbps dial-up modem. 10 years ago it meant not having access to 0.5 Mbps broadband. The bar is now significantly higher. And you don’t usually need 25 Mbps for NNTP, although the last time I actually used NNTP was over a 56Kbps modem.
