dict types to dict[Unknown, Unknown], not dict[Any, Any]. I'm the main developer on this code right now, so I've been pretty much ensuring its all typed reasonably well myself, but I don't just blindly trust it. I check what types it thinks it is, reason why they aren't as narrow as they could be, and fix that to make them more narrow, sometimes introducing extra classes so I don't have to type them as dict[dict[dict...]]. This is also an established codebase that does server-side processing that flask makes easy, and most of the developers working on it don't know C++ or Rust
