I'm confused. From what I see the number of classes is currently fixed
in the instance header. As if it was static. I suppose you can work
around that limitation with some hacks but I want to use a clean API
for that.

Or is there a recommended way I'm missing?

that keeps track of which labels have been seen so far, by reading that data out of the instances.
