It looks like them taking out an attempt to ensure PRNG is seeded by throwing some data at it. Worst case scenario is that it has no effect, you can't lower entropy in a pool by adding data as long as you have a working hash function.

We know that with DSA the entire security of the signature depends on having a good random source, unless you are using a deterministic scheme, but that's a different function.

In this case it looks like they are taking out possible entropy sources just when entropy is most required. Why is this a good thing?
