btw - the current plan is to add a build rule that generates the .json file
automatically as a pre-requisite of building platform.dill.

One detail that is trickky is that the generated .json would be in an out/*
folder, so we'd need to adjust all relative URIs to the new location (or emit
them as absolute uris)

Let's discuss this plan at our next 1:1.
