comment An unfair marriage lemma
@David: Because we tested it on live analysts. It turns out that the very language of graph theory is not as widely understood as one might hope.

comment An unfair marriage lemma
Thanks! I tracked it from Mirski & Perfect's paper down to Dulmage & Mendelsohn, Coverings of bipartite graphs, Canad. J. Math. 10 (1958) 517-534, Theorem 1. And there (unlike the other sources) it is exactly it, not something that one has to combine with Hall's Theorem.

comment An unfair marriage lemma
Yes, we have the very same argument. It would be 5 lines long if we were aiming at combinatorialists. But it took more than a page to make the text consumable by analysts.

@darij: Yes, of course we will prove it in the paper if there is no reference. It just looks too natural to be unknown.
