Comment 2 for bug 1649198

OK. But what would the function definition be?
Can the value change under the hood in the middle of planning?

My intuition is that we should scrap the whole idea, get back to just load-op by default, and leave bundles be a matter of delivery only.

Is there any advantage to using bundles during development? Is the advantage worth the complexity? If you often want them, can't you "just" write your own function instead of load-system that calls operate with 'load-bundle-op? And/or use "make" and :build-operation?
