Ok, I got confused I guess, there was a dual colour coding scheme in play
in the original diagram. Should the boxes be light vs. dark blue instead?

I do think it's fairly radical. I've been trying since yesterday to think
of other platforms that perform shared-file-based service orchestration
(i.e. BDP+-on-S3), and none come to mind. As for how much that is actually
the plan, I'm now more confused than ever.

I have a (very) long trip.

Hope it goes well!
