wait what?That's just the thing! Conjuration isn't the summoning school, it's the 'create stuff by pulling materials out of the planes' school. Stuff like... fire or acid.
a logical and thematic understanding helps build out ideas for wizards and makes it easier for the designers as they know where things belong.Sure it makes sense. When all is said and done, all arcane magic is manipulating energy in some way or another, after all. Arcane magic in the Realms is tapping into the energy and forces of the Weave and shaping them. Arcane magic in Dragonlance is pulling power from the Moons and shaping it. And so on. For divine and primal magics, you're a conduit for the power of godly or elemental/fey beings to channel through, but its the same idea. Energy moving around.
There's no need to force D&D magic into Fantasy Thermodynamics, Fantasy Laws of Motion, Fantasy Chemistry, and Fantasy Biology schools just because there's some similarities. Magic can follow its own rules.
Why would someone consider Shield and Protection from Good and Evil the same school? They both protect you. One is a shield to protect against physical attacks, one is to protect against eldritch forces, but I bet they could have the same basic spell structure - a shell of magic protecting the body and soul, attuned to "block" different types of energy: Physical force, divine and primal forces, etc. Even Dispel and Counter could be considered the same, by creating a shell that blocks energy and disrupts its spell form, rendering it null.
Why isn't there more done with spell schools? Because, lets be honest. This is a game that specializes in dungeon delving and killing monsters, all while taking loot. Not a magical academy nor a wizard research hub, Strixhaven aside. The details simply don't matter for the majority of games, and even then, some of the details change between settings, so an in depth dive into the exact science behind magic would be... kinda pointless.
you do not need science just a reason things are beyond the superficial.
