Isn't "bx seed" supposed to be weak? I mean the docs clearly state that this is generating a "pseudorandom" seed and can "introduce cryptographic weakness". Why would a wallet use this in first place?

Or is the problem somewhere in the code affecting other commands like "bx hd-new" because the doc doesn't say anything about being weak there.
