I do not see how you are describing a practical coding situation here. I do not start with a dozen call sites all over the code base, and then write a function they all call. On the other hand, when adding a new call site that wants to pass ownership away, and the called function doesn't take a PassRefPtr, it's immediately obvious that it's not going to work.

Even when following a cargo cult rule is easier (not uncommon!), the problem of it being disconnected from the actual benefit still remains.
