Well, you might want to at least specify the types properly. Also, I
think some parts one would want to re-write to make them more idiomatic
to the target language. And finally, if you want to see the safety
benefits from Rust, you want to probably not like 50k LOC from C into 2k
LOC of Rust.  But you are of course right that one does not _have_ to
re-implement anything.
