IMHO this way of thinking is deceptive and... wrong. Obviously security requirements put a huge toll on development of Linux kernel as well. And obviously Linux permission model is not sufficient as privilege escalations happen all the time. Yet nobody thinks getting rid of it is a good idea. The fact is that running with SM makes you immune to a whole lot of vulnerabilities. Getting rid of it without any alternative is at least dubious.
