It is also why I am hopeful for our next Demi/trance to be Innocence as it is also one of those that lore-wise we have actually fully encountered. If we look at the MSQ encounters we have:
Garuda*
Titan*
Ifrit*
Shiva**
Bismark
Ravana
Tsukuyomi
Lakshmi
Susano
All Lightwardens
*Garuda, Titan and Ifrit I have included, though I hope we do not get these although the third Demi being a demi version of the currently summoned Egi would be pretty cool - though I feel it would also be a bit lacklustre as we've had so much of them already.
**Shiva included as we were present when Ravana defeated her and when she died, so, therefore, we could technically be bathed in her "essence" allowing us to summon them
Omissions: Niddhog - he's not really a primal and its suggested that his essence has taken residence within Estiniens weapon.
This list is comprised only of those we would face in the MSQ. I don't know if we can include those we have fought in side quests as potential summons.
I think it is logical we got phoenix as Bahamut and phoenix's Aether was intertwined and scattered when Bahamut was originally defeated, thus meaning everyone got a bit of it.
edit: added clarification around why Niddhog omitted.
