Assuming nobody looks at the requirements of the problem to write a single line of code in order to tool up to the task.
On the other hand, now that the "we need to undo all this" use case actually needs to be used, they've gotta go back and solve the problem after the fact. Unsurprisingly, it's going to take a while to develop that solution.
I'm not excusing it, but I do think it's interesting to think about the technical and political issues.
