# Models in the two decks may share an ID but not a schema, so we need to
# compare the field & template signature rather than just rely on ID. If
# we created a new model on a conflict then multiple imports would end up
# with lots of models however, so we store a list of "alternate versions"
# of a model in the model, so that importing a model is idempotent.
