Honestly, your list here just reminds me of there being little to no good reason for the removal of so many upgrade traits with Stormblood (formerly a good half of the total traits on many a job).
Previously, these gaps could be mitigated by giving lesser variants of each future powerhouse skill early on.
Now, so long as you get the ability at all, you instantly have all but its future additional mechanical interactions, meaning that if the endgame kit requires a certain level of strength for parity in endgame content, that same strength is thrust upon even a level 15, for instance, even if it will be some 45 levels until other jobs in the category get their own analogs or anywhere near parity.
While levels prior to level 30 are of course irrelevant to Astrologian, I wouldn't mind seeing, say, Essential Dignity being 200 potency at first at level <30, upgrading to 300 around 45, and its final 400 around 60, while White Mage, for instance, would trade positions the of Benediction and Tetragrammaton or reduce the cooldown of Benediction from 180 seconds to 120, giving it better synergy with Living Dead, or 150.
