Licensing is unclear

[gnidan]

This project does not currently state any license for public consumption or to inform potential contributors of their rights, if there are any.

It's unclear (to me) whether there's any added complexity here due to the EIP process requirement that all proposals be public domain. If we do intend to target an EIP as an output of this work, we certainly need to ensure that all contributors are aware that their work will be released without copyright.

Not sure if there's a reason to impose licensing constraints on non-EIP portions of this work (like, if we implement CI systems for formal schema validation, or build internal tools to generate code examples, etc. – is there any reason for this kind of ancillary stuff to reserve copyright?)

Seems worth just checking this one off quickly to prevent future headaches.
