Breaking the declarative format would be very bad, IMO. This format will need to be written and read by a number of tools in different languages. IDEs will need to read it to find imports and offer intellisense, etc. Web servers will need to read it to do server push. Package managers and build systems like Bazel and Buck will need to write it. Not all of these can easily or performantly execute JavaScript functions.

I think https://github.com/domenic/package-name-maps#a-programmable-resolution-hook covers this.

Yeah, this is covered in the readme :). It's not really a feasible direction for running in web browsers.
Additionally, this proposal is very strict on restricting itself to name resolution, and not any kind of source transformation. I think there could still be future ways to register custom Content-Type processors/source transformers, but it wouldn't be part of this proposal, and would have a lot of issues of its own to work out.
So, let's close this.
