Specifically on > it's good practice to periodically reseed the CRNG. And so that means you still need to have an entropy pool and some way of measuring how much entropy you think you have accumulated, and how much has been possibly revealed ("used") for reseeding purposes Periodically re-seeding the PRNG can be argued to make sense, but doesn't require entropy estimation: consider https://en.wikipedia.org/wiki/Fortuna_(PRNG) https://en.wikipedia.org/wiki/Fortuna_(PRNG) (and the paper mentioned under "Analysis".) Not needing to estimate entropy does come at the cost of a longer time-to-reseed, but that still seems a good trade-off to me. (Just in case you weren't already aware of that design.)
