Also aliased as: zeitwerk_original_require

zeitwerk_original_require(path)

Zeitwerk's main idea is to define autoloads for project constants, and then intercept them when triggered in this thin `Kernel#require` wrapper.

That allows us to complete the circle, invoke callbacks, autovivify modules, define autoloads for just autoloaded namespaces, update internal state, etc.

On the other hand, if you publish a new version of a gem that is now managed by Zeitwerk, client code can reference directly your classes and modules and should not require anything. But if someone has legacy require calls around, they will work as expected, and in a compatible way. This feature is by now EXPERIMENTAL and UNDOCUMENTED.
