Fun & cursed fact, the ArchWiki has a rather long section on dual boot pairing. Pair in Windows or Mac then painstakingly extract various bits of pairing info from the OS and toss it into Linux, so you can dual-boot & keep the pairing. https://wiki.archlinux.org/title/Bluetooth#Dual_boot_pairing

I've always wondered how feasible it would be to copy Bluetooth pairing information. This particular series of hacks seems to rest at least somewhat on it being the same Bluetooth host adapter. (But maybe the host side can spoof, trade IDs with the other device?)

Ideally I'd love to centrally and dynically manage what devices of mine are paired with what system... I think that might be technically feasible, as long as I'm not trying to pair multiple things with a single bt adapter.
