Debian has something called multiarch: https://wiki.debian.org/Multiarch
From my understanding, it allows you to boot a single install on multiple different architectures.
Does gentoo have / plan to have something like this? |

Isn't that for x86/x64 only? I mean like being able to boot on both x86 and ARM. |

Not even the Debian page you linked to suggests that, their use cases are multi-ABI arches or emulation/cross-compiling. |

This is not traditional multilib. Multilib has lib32/lib64, where it is understood from the host CPU architecture whether lib64 means amd64, ppc64, aarch64, etc. The Debian page proposes that architecture-qualified directories be named for their target architecture, so that you can have amd64, ppc64, and aarch64 directories as peers, rather than lib64 as the native 64-bit (whichever one that happens to be) and the other two be buried off in paths designated for foreign architectures. |

Oh... that probably wouldn't be impossible to do. It's a matter of tweaking ld.so.conf and $PATH to look in /usr/$ARCH/, which crossdev already populates... |
