Yeah, I do not think we are doing this because the current code is
completely broken and everybody needs to move to CSPRNG that makes
it absoletely safe---rather this is still just making it safer than
the current code, when system support is available. So a fallback
to the current code would be a good (and easy) thing to have, I
would think.
Thanks.
