I think the only mechanical import of school in Starfinder is when you use Detect Magic and the minor divination boost for a technomancer using the harrow deck thing as a spell cache. We're not going to see school specific DC boosters or extra spells known, which was why it really mattered in Pathfinder.

I mostly agree with you however there are more exceptions then just that. For example take a look at the spell Break Enchantment.

Break Enchantment:
"This spell frees victims from curses, enchantments, and transmutations."

Earlier Luck argues that Inject Nanobots sounds like a Transmutation Spell, but it is instead categorized as a Necromancy. Well if it were a Transmutation then Break Enchantment would work against it...(I realize that Break Enchantment has 1 minute casting time but technically Inject Nanobots can last longer at 1 round per caster level.)

Additionally I would like to point out that there are certain aliens and items which have interactions with specific magic schools. For example, Embri from AA2 have a +2 racial bonus to saves against enchantment spells while wearing their mask. They are not alone either, several other alien races have bonuses to saves against specific schools.

Another example would be the magic item Iomedaean Crusader Helm, which allows its wearer to roll a saving throw twice, taking the better result, against Illusion and Enchantment spells cast by evil outsiders.

I admit that most of these examples are fringe cases, but I'd be surprised if similar abilities/interactions with the spell schools don't get added to the game later.

Looks like I misremembered which schools had the least spells.

Illusion and Necromancy are tied for the least spells at 18 each. Evocation has 21.

Transmutation on the other hand has 42 spells.

I'm not sure why they added extra rules and a confusing spell description to fireball. Wait... I mean "Explosive Blast".

What do you think about Telekinetic Projectile being Evocation while Telekinesis is Transmutation? They have very similar effects.

I'd also like to add that I've previously generated a list of Starfinder spells organized by school. If I remember correctly, Evocation and Necromancy had the least spells by far while Conjuration and Transmutation had the most. I wonder if that factors into how these are categorized.

I don't find much in Starfinder which explains what the different schools of magic do. However we can look at Pathfinder as the source.

In Pathfinder, Necromancy deals with the manipulation of the essential life force which infuses all living things.

I'd argue that since you're converting key particles of your blood(life force?) into nanobots(mindless unliving things...) that it isn't too much of a stretch to be categorized as Necromancy.

Additionally, I'd agree with you that Corrosive Haze should be in Conjuration. You can find a thematically similar spell in Pathfinder called Acid Fog which is Conjuration.

If you want more spells to be upset at, take a look at Fabricate Scrap(Universal), Junksword(Conjuration) and Junk Armor(Conjuration) all of which in my opinion should be Transmutation.
