ACLs, Appcontainers with capabilities, etc have been something in the OS for more than a decade.
(I agree that maybe applications could’ve been built for 3.1/9x and expect a single user, but the os expects multiple).
The only way forward is a better system architecture, as enabled by the seL4[0] microkernel.
Any solution involving keeping Linux or the monolithic kernel is just stopgap or outright delusional.
