Or you could remember that one of the core unix philosphies is "tools,
not policy" and leave it to embedded systems developers to decide for
themselves what's "safe" or not.  Not every application needs
cryptographic strength entropy, especially for things like retrying
after a short random delay or generating a random MAC address or
whatever.
