internal/codependencies/README.md

-This package allows us to depend on other modules, to _force_ these other
-modules to upgrade to some minimum version. This allows us to express "co
-dependency" requirements in cases where this module doesn't strictly speaking
-_depend_ on another module, but conflicts with some version of that module.
-We are using this here to depend on deprecated modules that have been
-merged into this package. 
-
-In practice, this means:
-
-1. Packages imported here _will not_ end up in the final binary as nothing
-   imports this package.
-2. Modules containing these packages will, unfortunately, be downloaded as
-   "dependencies" of this package.
-3. Anyone using this module will be forced to upgrade all co-dependencies.
