Nobody's aiming for perfection. We're discussing aiming for "better". What we should have done on day one was to set the default MLOCK_LIMIT to zero bytes. Then everyone would have infrastructure to tune it from userspace and we wouldn't ever have this discussion.
Setting aside perfection or not, what you're aiming for is about 1000× more work. I'm not prepared to do that work. I'm not going to paint this same bikeshed 100 times for each Linux distro we have to convince to adopt a more sophisticated solution.
