Well, you're right, it is retrievable, but the problem is you might
never know that the code got dropped until the problems surfaces,
perhaps as a defect in production. Then, after much pain, you isolate
the problem and resurrect the code.
It would be much better to get a conflict notification of some sort,
something like "rename of foo conflicts with change or foo".
