Most people stick to default options, and this one looks worryingly short. I personally love the idea of using Diceware words (specifically, the EFF shortlist version). Fairly high security can be achieved with 3 only or 4 words (at 10 bits of entropy per word, you get a billion possibilities with just 3 words). Maybe Magic Wormhole already has that option, I haven't checked. In any case, I would like whatever is the default to be raised to at least 20 bits of entropy.
