I've tried it this way. You can get away with no TTL if your keys are constrained. Sometimes there are enough keys to be a problem. I'd rather just set up a TTL and not worry about this.

Agreed, simple and widely applicable heuristics are great, and you can think deeply on it when and if it proves to be an issue worthy of such attention.
