Please see my answer to James and Leon, i.e. if we have abstractions
for a particular subsystem, it should mean somebody is happy to write,
use and maintain them.

That means that, yes, for subsystems that have Rust abstractions, if
you want to touch the C API, you also need to do so for the Rust
abstractions. But for any heavy refactor, I would expect maintainers
being the ones doing it, or at least helping to do so if somebody else
wants to change something in the C side and does not know how to
update the Rust side.

Cheers,
Miguel
