You could make that same argument for any parallelism - your CPU queues some inputs and processes them in an arbitrary order after considering dependencies.

There's a long way between hand-writing CPU instructions to make sure it does the same thing between runs, and the other extreme of writing a terraform yaml config and letting the engine decide how to get there.

Excel is so far from SQL/YAML that I can't lump them all together as "declarative". "Column from examples" comes to mind as a more declarative Excel feature than formulas in general.
