should upgrading *some* dependancies be considered a breaking change
Upgrading some dependencies can break downstream integrator. In particular, going from rusqlite
0.27 to 0.28 prevented a seamless upgrade of onionmasq from arti-some-old-version to arti-1.1.0, because 0.27 and 0.28 can't live together apparently.
