Ah. I see nothing wrong with that, for the same reason I see nothing wrong with setuid (the system call) after PR_SET_NO_NEW_PRIVS. The privileges granted by writing to /proc/self/attr/current were already available in the sense that you could have written to current whenever you wanted to. (FWIW, I think that selinux should have made that the only way to change contexts, full stop. And I think that the setuid and setgid bits were mistakes.
