It's a little less clear than that, unfortunately. Apple chose to not support third-party Bluetooth LE dongles, which might be a reasonable engineering limitation. However, if you upgrade your Mac with a BT-LE capable board used by other Continuity-capable Macs, you still can't use Continuity by default; you need to patch some kexts and disable kernel kext signing[1]. It really does feel like Apple blacklisted older machines from using Continuity; only third-party kext hacking can get things started again.
