// ElementProto is the union type of all _elements_, which are the foundation
// of how we model schema changes in the declarative schema changer.
//
// A core design principle is that each element owns its back-references, that
// is to say, it is responsible for updating any back-references in the
// descriptors that it references as part of its lifecycle, i.e. going from
// ABSENT to PUBLIC or vice-versa. As a corollary, back-references are not
// modelled as elements at all, they exist purely as a side-effect. In an ideal
// world, they would be modelled as elements just like everything else, however
// we currently don't have 1:1 relationships between forward and back-references
// in all cases: we do for foreign keys for example, but we don't for type
// references (back-references are modelled as a set in the type descriptor).
//
// Regardless, this principle does have the inherent virtue of keeping the
// element model relatively simple, if at the expense of pushing the complexity
// down to the execution layer in scmutationexec. This trade-off is acceptable
// though: the back-reference update code is quite self-contained and the
// added complexity consists in making these operations work on a best-effort
// basis, i.e. with not many assumptions about whether something is dropped or
// not, etc.
//
// A less strong principle is that each element should remain immutable
// throughout its lifecycle. In practice we sometimes deviate from this for
// elements which have only just had targets defined for them and thus haven't
// yet undergone any status changes. In any case, that kind of hackery is best
// kept at a minimum.
