That seems like a completely different concern than what you originally stated? You're not worried about future policies, you're worried about the policy that was just passed.

And for what it's worth, it seems like they only care if the project is directly crypto related (e.g if you had a repo directly implementing a Monero node, that would probably not be allowed). If it's just a repo that implements a generic Cryptography concept that happens to be used both in crypto and elsewhere, then I don't see what the problem would be.

Again, the rules are judgement based. That means you can interact with the community to get clarification, and make your case that your project is worth keeping.
