- prometheus is now behind an interface, they aren't dependencies for the reusable components anymore. - some dependencies have been inverted: instead of packages importing a main package to get configuration, the main package now sets configuration in these packages. that means fewer internals are pulled in. - some functions now have new parameters for values that were retrieved from package "mox-".
