This seems like a easy way to get into consulting. Once you deliver the code back to the owners they are going to do the vibe coding again on the top whatever refactored code you get back. In other words it can become a perpetual cycle.

The goal is to avoid it and build such a structure and guidlines for the codebase, so it can refactor itself when needed, but based on the architecture defined by us. With good set of docs and new feature definition you can most of the time use /grill-me with good outcomes.
