They're fairly low risk, but you tend to leak a surprising amount of
information when you expose non-cryptographic random sources to
attackers.  We've already gotten a rather detailed report of the leaks
from Math.random, for example.  If these functions are useful, we can
keep them, but it does cost some amount of attack surface.
