Hmm, that's probably it. Although, some of the summoned dragons (like White Rose) had breeding rarities rather than "unbreedable" even though their descriptions said "not found through breeding", so maybe dragons like these are planned to be breedable in the future like they did for Clockwork... Who knows.
