Slave Latency

Does anyone know why Apple limits slave latency to ≤ 4?

For use cases where there is only an infrequent transfer of data, it would seem that allowing a peripheral to request a larger slave latency would allow the peripheral device to save significant power.  This is providing the peripheral can be implemented to not listen and respond on every connection interval that there is nothing to respond with.

For example if I were building a BLE mouse or keyboard, I would want a high connection interval to respond quickly when the user was doing something but not respond when the peripheral was connected and sitting idle.
