Another good thing pointed by the article would be to use the
Mersenne twister for unpredictableSeed, which would make it
difficult to infer the sequence from a few samples. Please
share if that would be a good thing to do.
"From just a few samples" yes, but in general the internal state
of Mersenne twister is easy to reverse – e.g. check out
https://github.com/fx5/not_random for a nice little demonstration.
IMHO there is no problem with unpredictableSeed not being
cryptographically secure, as long as the docs point out it is not
to be used anywhere near where a CSPRNG should be. But I'm hardly
an expert either.
