I'm a bit confused why this didn't change memory usage at all, given that it should have removed an entire query 😕

I'm a bit confused why this didn't change memory usage at all, given that it should have removed an entire query 😕

We only diff memory usage on four projects currently: https://github.com/astral-sh/ruff/blob/main/crates/ty_python_semantic/resources/primer/memory.txt. It might be worth expanding that list (if it means that the memory-diff job takes longer, we could consider having the memory usage reported in a separate comment so that we still get quick feedback on the diagnostics diff of a PR). I think sympy would be a very interesting one to add to the list, since it's a larger project that we have quite high memory usage on IIRC
