Anubis is significantly less jarring than cloudflare blocks preventing any access at all. At least Anubis lets me read the content of pages. Cloudflare is so bleeding edge and commercial they do not care about broad brower support (because it doesn't matter for commercial/sales). But for websites you actually want everyone to be able to load anubis is by far the best.

That said, more on topic, I am really glad that C++ actually considers the implications of switching default targets and only does this every 5 years. That's a decent amount of time and longer than most distros release cycles.

When a language changes significantly faster than release cycles (ie, rustc being a different compiler every 3 months) it means that distros cannot self-host if they use rust code in their software. ie, with Apt now having rust code, and Debian's release cycle being 4 years for LTS, debian's shipped rustc won't be able to compile Apt.
