   > One core distinction here is that the tir_to_runtime hook isn't a pass, it's an override of code generation.
   
   Ah, excellent, that's where we've been trying to get to but when we started this conversation the refactoring to support it seemed to much to foist upon you. But we've now (thanks Lily!) extended IRModule to be able to support a mix of Functions and target-specific PrimFuncs, so it is now conceptually possible to run multiple lowing passes in series and have each only focus on lowering the Functions they care about based on the compiler tagging. With luck it's just a matter of working through the usual surprises and glitches.
