Okay, you're the boss. The conversation did go pretty far afield but the main thing I wanted was just that if a user wanted to have annotations from framework 1 and framework 2 they could reliably express that as

def foo(a: [Anno1, Anno2]): All that that requires is a statement in the spec saying: "If you're processing annotations and you see an annotation you don't understand, skip it. And if you see a list, look inside it rather than processing it in some proprietary fashion."

So, time for an embarrassing confession: I had a bit of a eureka moment this morning, and I think I finally understand where you were coming from with this idea. I honestly don't know what I thought you were proposing, but now that I get it, my old conception seems like rubbish. Consider the dict-based proposal withdrawn.

Apologies for my part in dragging this discussion into a triple-digit comment count : )
