I would call your attention to the several places it was demonstrated for use by libbitcoin team members -without- a warning, such as in their contributed examples in Mastering Bitcoin. We cover a few of such examples in the writeup.

Also note that the tool bothers to refuse to use a flag to specify 32 bit seeds, due to their known risks, but then proceeds to give you only 32 bits of entropy anyway even if you ask for 256.
