You can supposedly still use 4.5 4.6 on Big Sur if you do the following but I have not tested it on Little Snotch, works fine for personal software and others ...

codesign -dvvv littlesnitch.package name

Save the team identifier

Boot into recovery mode

Open terminal and type the following...

spctl kext-consent add <team identifier>

Reboot into normal user mode and install version 4

The fact that there's a highway to Hell but only a stairway to Heaven says a lot about anticipated traffic volume.

 So after installing Little Snitch and basically denying "trustd" any kind of Internet access, I have been seeing reasonably normal jitter with Bluetooth enabled.

I actually “saw the same” on Catalina while using little snitch. 

“Saw the same” after installing yesterday Big Sur and suddenly received a notification “this version of little snitch is no longer supported by macOS. It’s looks like I have to pay 25€ for a new compatible version. 

It's not that Bluetooth stops scanning, but it's not scanning as aggressively. So after a few minutes, there will be very high jitter when Bluetooth scans the environment, but it would affect only a single packet. It's easily reduced its chattiness by 99%.

I don't have any empirical data to support the claim that Little Snitch has anything to do with it (and I am too lazy to dig further into it), but the reduction in jitter is massively noticeable since Little Snitch. Which means I can now run Catalina with Bluetooth enabled and not have any wi-fi problems.

Just FYI, for the archives :-).
