These are the relevant lines from the policy: 2.7 Apps that download code in any way or form will be rejected 2.8 Apps that install or launch other executable code will be rejected And I suppose this covers use of W^X / mprotect: 2.5 Apps that use non-public APIs will be rejected

mprotect() simply returns EPERM. The kernel enforces W^X; once a page has gone writable, it can never be executable, and vis versa.
