This is a bit like focussing on a leaky tap in a burning building, given the other more serious problems with Spinctrl. I know attention to details matters, but not at the expense of the whole picture. I think this is why Spinctrl got broken in the first place! Too much specialisation... Not good for science in general. Certainly not good for code.

That said, I'll bite. :) It's still worth discussing. I see your point, but I have other calls to FeedBack() that have an ID, are not event driven. If I could test for variable type at the start of FeedBack() this might work, possibly? I don't know if the event passed to a variable HAS a type. in the Lua sense of the word...
