I was fairly certain that the Onion Soup project in Blink is eliminating the
need for public/platform/* data copying. Instead we're using Mojo to directly
communicate between Blink and its embedder. We have been able to avoid files in
public/platform/modules/payments/* so far. Let's continue this trend. Please
redesign using Mojo instead. See components/payments/*mojom for reference.

Sure, I have already followed Onion Soup project in the last few CLs.
Here are my other CLs.
 - https://codereview.chromium.org/2472723003/
 - https://codereview.chromium.org/2476343002/
 - https://codereview.chromium.org/2497983002/

Event dispatching parts will also use mojo (in follow-up CL), but it will
connect the content/browser to content/renderer.
In service worker perspective, it's difficult to connect content/browser
to Blink directly right now because the ServiceWorkerContextClient and
others are still in content/renderer side. (In other words, we should move
SW related codes in content/renderer to Blink first.)

shimazu@ is working on mojofying service worker actively.
Please see his comment in #10.
Also, you can see Step3 in his design document:
