Migrating to Bazel Modules (a.k.a. Bzlmod) - Module Extensions
So far, we've covered relatively easy Bzlmod fixes, how to hold runfiles and
pkg_tar correctly, and how to access canonical repo names when absolutely
necessary. Now we'll discuss replacing WORKSPACE statements with your own
module extensions. You can use them to wrap your project's setup macros, and to
adapt external repositories that aren't Bzlmod compatible to work with your
Bzlmodified project.
