such a reasoning is pretty much wrong on all levels. An out of range
device might never come back in range and you end up with a device on
the connect list forever. And if it ever comes back, we end up with some
unexpected connection attempt to that device.

The only sane approach would have been to add a timeout and just abort
the pairing attempt after it. Everything else is just trying to fix a
symptom and making it actually worse while doing so.
