rust-bus crates are possibly unmaintained

[simonsan]

I just discovered https://github.com/rust-bus to be unmaintained and archived. They have a lot (possibly 118) of (now unmaintained?) crates on crates.io: https://crates.io/teams/github:rust-bus:maintainers

Does this need a security unmaintained crates advisory?

I couldn't extract information regarding this special case from https://github.com/rustsec/advisory-db/blob/main/HOWTO_UNMAINTAINED.md

54 crates they maintained on crates.io are updated within the last year.
The other 64 crates have been updated the last time over more than a year ago. Which makes me think, that rust-bus maintainers could be one of the main maintainers of these crates, and it might be warranted to assume they are now unmaintained?

I don't think this calls for a general action for all impacted crates (which also matches the approach adopted by the crates.io team). Most of these crates should have other maintainers, and in this case our usual maintenance policy applies.

However, crates having only rust-bus as maintainer on crates.io are probably worth an "unmaintained" advisory.

Rust-bus was used a backup. The org didn't actively intervene, so the de-facto maintenance status of these crates hasn't changed.
