Questions about CodeGen

[pl0301]

Hello, I reviewed the discussions about code generation, and I also looked at Smithy's specific implementation of code generation. A question arose for me: why does code generation directly consume IDL and follow the path IDL -> code, rather than IDL -> YAML -> code? The second approach could fully leverage existing code generators, and I don't see any advantages to the first approach. Is it just to win what Nordic referred to as the "definition war" over API specifications?I would appreciate it if you could clarify my doubts.
