Thoughts.
At all of these levels, the number of spells available is heavily weighted towards Arcanists, but not likely to affect most players in any case. The list is really like a dream board in any case.
Still, a 3:1 ratio (e.g. Arcane to Divine at level 9) seems pretty extreme, and there is no reason for bigger gaps:
I'd like to see another two level 7 Primal spells, and another 8th level Divine spell at least.
Based on these lists, they are keeping all the PHB spells, though some are reassigned to different schools. I was half-expecting that all the Conjure creature spells would be removed, and the Summon spells (like Summon fiend), which give a stat block of the creature summoned and not choice from the MM, put in their place. That still might happen, of course.
This could be taken to suggest something about the backwards compatiility of all the spells in Tasha's and Xanathar. There will need to be some rule aboiut which spells belong in which spell list (even "if it was on the list for a class in 2014, it is part of that class's spell list still").
