I don't think run0 uses the same configuration syntax as sudo, so it's a no-go from the start.

sudo-rs can be a drop-in replacement for sudo for at least 95-99% of deployments, without any config changes necessary.

Now the rewrite in Rust is important because it greatly prevents appearance of new, memory-based bugs. Which might inadvertently happen if, say because of fixing a logic bug in one of sudo's more complex usages (and thus, less traversed code path), the maintainer introduced a memory bug.

This resistance, IMHO, is moot anyways since the sudo maintainer himself is in support of sudo-rs and actually helped the project in a consultancy capacity (as opposed to directly contributing code).
