At least one crate, propolis-server, is a dependency of omicron-common strictly for the purpose of being "available" to be built via cargo build -p propolis-server via the omicron-packager utility. This is a bit unfortunate, as it means the Propolis server, and all its dependencies are built when building anything else which depends on omicron-common.

It would be nice if propolis-server, and any other dependencies present (only) for the same reason were split out in some way so they didn't otherwise pollute the dependency tree.
