I don’t mind, but maybe it’s still enough progress that we keep it, and then we have all your refactoring (including input messages) in one place?
(Here, I’m concerned about tracing the evolution of the code. The step I did seems obvious from the existing code. Maybe yours is too? Not having looked at it yet, I don’t know)
I don’t mind either way.
