This is probably never going to pass tests with the change in semantics for complete. We can no longer rely on the parameters of a completed system being the same as what was defined when creating the system, which I think a lot of tests rely on.

We can also no longer rely on issetequal(parmeters(sys), get_ps(sys)) for a flattened system.

Let's see how this turns out. If something like what you suggest is really changing it would be one of the largest changes to Catalyst ever, probably after moving to maps as inputs to problems. Would probably take ages to figure out all the implications.
