Both FastAPI and SQLModel are removing deprecated slim package stubs that have lingered unused for months, signaling a focused push toward cleaner dependency chains.
FastAPI dropped its slim package stub [1], a deprecated compatibility layer that served no purpose for months and was kept only as a precaution. SQLModel followed suit the same day, removing its own unused slim stub [2] to match. The parallel cleanup across both Tiangolo projects suggests a deliberate housekeeping cycle to reduce packaging surface area and eliminate dead weight from the dependency graph. In a separate move, SQLModel is automating its release preparation workflow [3], borrowing patterns from asyncer to streamline the path from code to production. These aren't flashy features, but they're the kind of maintenance work that prevents future pain when version bumps slow down because of accumulated technical debt.
