Hmm. What do those systems do for cryptography? Just assume it won't work and not rely on it at all?

In these kinds of systems the cryptographic components often aren't even accessible from the software. It isn't a thing you need to worry about.

This makes it easier to audit for use of entropy sources in the software since there really isn't a valid use case for it.
