I think more of an on/off flag with some additional parameters. And it
maybe described the best with "Automatic Sniff Mode".

It can be useful for all kind of devices where power consumption is
essential. Even an iPAQ with a PAN connection can profit from it. The
Microsoft HID devices make heavy use of sniff mode, before they
disconnect the ACL link after 12 minutes of idle time. And everyone
talks about the long battery life time of Bluetooth HID devices, so this
looks like the right way to reduce power consumption.
