    What is the purpose of giving all those rules? Would anyone actually use them instead of just using the definition? It seems to make it look unnecessarily complicated.

    Removed the reference to “subtype proposition” as the propositional truncation of the type of embeddings. I’m confident that that is almost never a useful notion of “subtype”.
