Description

With robust, native ES module support in both the server and the main thread of modern browsers, it would be wonderful to have full support for ES Modules in Web Worker contexts without need for compilation.

Rationale

• Ease of code reuse
• Syntax isomorphism between main thread and workers will make it easier for devs to pull work off the main thread and increase page responsiveness
• We're so close! (Firefox is missing support)
