This seems to be solving a problem quite similar to the one of getting browsers to resolve non-relative imports (without file system access, they also need a precise map from module names to paths). Unfortunately, I can't remember who or what was working on that and I'm not sure how much progress it is making, but it'd be wonderful if this could somehow be framed in a way where it also helps that issue along. Are you taking this into consideration in the design?

I think you're referring to the package-name-maps[1] proposal. We've been made aware of it during the middle of the development, and while we chose to continue using the static data tables approach, they aren't incompatible.

The reason we abstracted the static tables behind a JS api is precisely to make it easier for everyone to experiment with various implementations - some might use the internally embedded data as we do, some could consume a package-name-maps file, and some could do something entirely different. As long as the contract described in the document is fulfilled, everything is possible.
