This is not done for Zod's benefit. It's done for the benefit of libraries that depend on Zod, and the users of those libraries. If a library wants to add "incremental" support for Zod4 (that is, without dropping support for Zod 3 and publishing a new major), they need access to types (and possibly runtime code) from both libraries to do so in a sound way. I detail a number of other approaches for achieving this here[0] and why they ultimately fall short. Ultimately npm wasn't designed for this particular set of circumstances.
