Wi-Fi is a useful comparison, but the use cases for Wi-Fi and Bluetooth
are different, and the current policies for all four aren't necessarily
permanent.

* Whether Wi-Fi scans for new networks in the background: That might
always happen now, but it's not set in stone. To save battery, we might
decide that Wi-Fi should stop (or at least, greatly curb) scanning for
new networks in the background whenever you are already connected to a
network.

* Whether Wi-Fi starts a scan when you enter the Settings screen: Maybe
it doesn't currently, but maybe it should, depending on how long ago the
last automatic scan was.

* Whether Bluetooth scans for new devices in the background: Currently
it probably shouldn't, because Bluetooth is currently used only for
connecting a device, and that should always be a manual operation. But
if we used Bluetooth for other things in the future (such as creating
ad-hoc networks), that might change.

* Whether Bluetooth starts a scan when you enter the Settings screen: As
I said, I think it should, because no automatic scanning means the
cached list of devices is very likely to be out-of-date. But as for Wi-
Fi, if your device had recently scanned in the background, there would
be no need for a new scan.

I've often observed that the word "should" in a bug report summary is a
danger sign: it indicates an assumed solution to an often-underspecified
problem. It seems that your real problem is "Doing a scan effectively
delays my ability to use the configuration options", but I don't see how
automatic scanning would cause this. Can you give an example, or even
better, a video recording of it happening? I don't see how scanning for
new devices would delay you from changing any other settings, because
all other settings are placed above the changing list of unpaired
devices. And even if it does interfere, probably there is a solution
that doesn't involve making scanning manual.
