RSG (Ryan Specialty Group) recently announced a rename to Ryan Specialty (no
"Group"), but I'm not sure if the legal name has been changed yet or not, so
I'll wait on that.
Cargo's default behavior is unfortunately to issue network calls each time
it is invoke in order to check for dependencies updates. This is not only
bad for reproducibility and privacy, but it's also a concern for supply
chain attacks, since most developers are unaware that this is occurring.
Instead, we pin to the lockfile. Installing dependencies can be done with
`cargo fetch` and updating dependencies must be explicitly done by the
developer, with the lockfile updated.
