IIRC, poudriere pulls it in on its first build for rust, before I've
switched to -devel. Not sure it's actually used or not.

But running rustc itself is very, very, very heavy job. It eats up all
6C12T even if only one rustc "process" is running, watching ps.
Maybe it is multithreaded and attemps to use all core, including HTT
ones, available. hurts severly with UI experience.
This is why I try as much proposals as possible for scheduler.
