Well, at least a couple of years ago, one surprising thing I discovered with rustup was that unlike distros that have a clean install/uninstall, rustup was rm -rf * ing everything in the place it was installed. There was an open bug on it and multiple complaints. I, who needed it for various system builds, had innocently rustup'd to /usr/local. On uninstall, it wiped all of /usr/local. I had backups on that machine, but it was still an unpleasant experience and I did lose a few not-too-important scripts. I don't know if others have run into the same thing, but it's why I'd trust Gentoo's packaging more.
