My thoughts exactly. Raids are in their own bubble, the only thing you need to do to progress is doing the raid and finishing the end quest of an expansion.
For Alexander you had to complete the Heavensward Quest (3.0 finale) and maybe a sidequest or two, but for the other tiers you just had to have done the previous tier and their quests. Savage could be unlocked the moment you finished the normal tier's quests.
Same for Omega, you had to complete the Stormblood Quest (4.0 finale) and then you could pick up the start of Omega, with the next tier being unlocked after you completed the previous normal tier and Savage, again, after you completed the current normal tier quests.
I think this might even hold true for Bahamut, but I didn't do it when it was current so I can't say for sure.

I really don't see them changing this any time soon. Heck, even the Alliance raids use the same set-up. They're all in their own bubble and just come after another, the only MSQ you have to finish is their relative x.0 MSQ.
