No. The implication is that C -> Rust makes the codebase of that solution much more complicated/uncertain than it needs to be.

The Rust language is just not stable enough to make sure the new code will last longer than the C counterpart as the language itself evolves.

And because Rust will always be slower than C due to the additional memory checks added by the compiler in every safe access, it makes the stability/security the main benefit from the conversion (as opposed to performance gains)
