Would it make sense to ask people to pass --show-seed or add it to their config? Should this module stop printing the seed in its own?

Might be breaking changes, but I'd be very interested to hear your thoughts (as it might mean changes to Jest would still be useful if there are blockers) 🙂 If the answer is "next major" that's understandable as well 👍

[dubzzz]

I added a small section recommending to add --show-seed into the Readme file. Concerning "not printing the seed via this library", it's definitely part of the plan. But as it would be a breaking I'll wait a bit before doing it.

Cool 👍 Nothing missing in Jest (as of now, regarding this feature)?

[dubzzz]

For now everything looks perfect ☺️
