Comment:

 I now remembered: constraints are deferred because it would otherwise be
 hard to construct topologies as the first edge in a ring of edges would
 need to reference the id of an edge which was not inserted yet... THere
 are probably ways to let the caller deal with deferring constraints but
 doing it at this time would be a behaviour change so I'd avoid to do that
 unless there's a very good reason.
