Would it be feasible to sed-replace the RHEL and/or Fedora selinux and container-selinux rulesets for use with other Linux distros?

AFAIU only SUSE can run both AppArmor and SELinux?

And browsers are running as unconfined in selinux with like all major distros; even on ChromiumOS (which was based on Gentoo, Gnome, and Chrome) where WASM or a paid shell (or 15-30% cut from the Play Store only) is the only way for the kids to Python on the Chromebooks we bought them for school.

Wouldn't it be great for them to not have to switch OSes and distros throughout the day.
