The piece that helps security-wise is that we're mixing in entropy from a trusted external source, so not solely relying on the local random number generation from a machine in a data center somewhere. Is it likely that local random number generation would be compromised? No. But it does give us a little extra peace of mind.

This is more of a defense in depth for the paranoid, but cryptographic PRNGs (and even hardware RNGs) can be compromised in ways that are not easy to find. Since they generate your keys, a compromise of the RNG chain is very valuable for a threat actor.

So, no.
