Description

Import maps currently have to load before any ES module and there can only be a single import map per document. That makes them fragile and potentially slow to use in real-life scenarios: Any module that loads before them breaks the entire app, and in apps with many modules the become a large blocking resource, as the entire map for all possible modules needs to load first.

This proposal is to enable multiple import maps per document, by merging them in a consistent and deterministic way.

Colleagues and I consider this a reasonable improvement to Import Maps. As such I suggest we mark it "position: supports" one week from now.
