I think that keeping an exact one-to-one mapping makes this tool a lot more useful. There's no telling what code depends on C idioms that would be broken by using a Rust idiom instead. Generating 100% equivalent code means that programmers can make intelligent decisions about when to switch over to Rust idioms as they continue developing the program.

Yeah, once you've got equivalent Rust, the rest is just optimization that should probably be implemented in the Rust compiler. No reason to put that stuff in the niche transpiler.
