But we assume there is some randomness to be had.
The cure is simple - mix in data from that RNG, but assume no entropy from it. This won't throw off the entropy estimate, but we'll get whatever entropy the device is capable of.
Someone may analyze the thing and get a better (but conservative) entropy estimate later, and get beter performance.
