I think so. Except you rarely use the `leaks` tool early in development. If this was baked into debug builds (with a way to opt out, of course), retain cycles would be caught much earlier in the development process and you'd see your leaks almost immediately after writing the offending code.
In fact, I'm pretty sure most people here don't check for leaks even in the final build of their app unless there's an obvious leakage problem. I know I don't, generally.
