Used to be Clang was faster than gcc (both compiling and the apps generated), but according to Wikipedia they now trade blows.
Some people are very much against the GPL. I don’t know why they put corporate interests over users interests. I assume it’s a cousin to “temporarily embarrassed millionaire” thought processes.
N=1, I like it when people make non-GNU systems work because I'm the kind of pendant who firmly believes that GNU!=Linux is a real and important distinction, and building Linux distros that aren't GNU forces the point. Unfortunately it appears that Gentoo relies on GNU coreutils, so this is just a baby step in that direction. On the other hand, Gentoo happily runs a prefix install on a lot of things that aren't Linux, and they have historically even run fully on a FreeBSD kernel, so they're still contributing from the other direction (Gentoo GNU/kFreeBSD, I guess). For nonGNU/Linux, Alpine is the reigning champion and Chimera looks super promising, but I'd love to see Gentoo as a good option.
Here's the bug if anyone is interested: https://bugs.gentoo.org/724314
