that was my goal with https://git.kernel.org/cgit/linux/kernel/git/sergeh/linux-security.git/commit/?h=cgroupns.v4&id=8eb75d2bb24df59e262f050dce567d2332adc5f3 (which was sent inline earlier in this thread in response to Eric) Does that look sufficient?Hmmm... but that wouldn't work with non-root and user ns.

Are you sure? IIUC that code block is only hit when we didn't find an already-mounted subsystem.
what's necessary is ensuring that namespace scoped mount never creates a new hierarchy but always reuses an existing one.
