Execution

Just for feedback
Why? It's a maestro concept. Why not have standard arg names for it?

Having it in the downstream system is a maintenance hassle. Every time we add a new feature, we have to add it in both maestro and the downstream system. We don't write the downstream system so this isn't always easy. We get inconsistent way of doing things cropping up. Fixes to maestro get applied at the level of the downstream system and not ported back to maestro. Etc ...

In theory, you could have logic that applies to all our loads that truly shouldn't belong in maestro, but I don't think I've seen that yet.
