Using the default R and rust kernels, runtimed will not report the kernels as "alive" always reports "unresponsive" For example:

╭─────────────┬──────────┬──────────────────────────────────────┬───────────┬───────────┬──────────────╮
│ Kernel Name │ Language │ ID                                   │ IP        │ Transport │ State        │
├─────────────┼──────────┼──────────────────────────────────────┼───────────┼───────────┼──────────────┤
│ py3.11      │ python   │ 6678141b-77c2-551e-81d7-7786bafb42bc │ 127.0.0.1 │ tcp       │ alive        │
│ rust        │ unknown  │ 24b212e1-a4a4-5dfe-b518-556926ed290b │ 127.0.0.1 │ tcp       │ unresponsive │

│ py3.11      │ python   │ 3581d36e-9c0a-529f-b362-7d0a65e71b5a │ 127.0.0.1 │ tcp       │ alive        │
╰─────────────┴──────────┴──────────────────────────────────────┴───────────┴───────────┴──────────────╯

The rust kernel will report this error message whenever runtimed tries to check it's status:

[/Users/cvaske/.cargo/registry/src/index.crates.io-6f17d22bba15001f/zeromq-0.3.4/src/pub.rs:130:33] e = Io(
    Os {
        code: 54,
        kind: ConnectionReset,
        message: "Connection reset by peer",
    },
)

which indicates that perhaps both the R and rust kernels are using zeromq messaging slightly differently than Python kernels.
