Can you find info to back that up. All I've seen so far is forceful
claims that's superstition ("These are not the droids you're looking
for"). Even the ssh-keygen man page has:

    The reseeding of the OpenSSL random generator is usually done from
    /dev/urandom. If the SSH_USE_STRONG_RNG environment vari‐ able is
    set to value other than 0 the OpenSSL random generator is reseeded
    from /dev/random.
