This sounds like an interesting idea. The best way to promote this would be to make a Swift package first, so that Swift users can use it right away and we can see how it works in practice. If it has sufficient merit and general applicability, then it makes sense to propose including it in the standard library. There are tradeoffs to increasing the API surface area of the standard library, so having experience with a SPM package first can help drive discussion.
