The (incomplete) saga of Bluetooth, ath(4), AR9565, and WB335.

(Please cc: me on replies - I'm subscribed nomail as this is likely a one-off question.) So, I'm trying to figure out whether Bluetooth can be made to work on my Lenovo Z50-70 (https://wiki.freebsd.org/Laptops/Lenovo_z50_70) running 12.2 (and soon 12.3), with 13.1 an option when it hits RC stage or maybe BETA. Relevant lines of /var/run/dmesg.boot show ath0: <Qualcomm Atheros AR9565> mem 0xc0400000-0xc047ffff irq 19 at device 0.0 on pci2 ath0: WB335 2-ANT card detected ath0:Bluetooth Antenna Diversity card detected kldstat -n ng_ubt.ko shows the module's loaded: 34 1 0xffffffff834d1000 4260 ng_ubt.ko but the "ubt0:" line https://docs.freebsd.org/en/books/handbook/advanced-networking/index.html#network-bluetooth led me to expect in /var/log/messages isn't there. Checking the wiki led me to https://wiki.freebsd.org/dev/ath_hal%284%29/BluetoothCoex (8 years old) where the "? - AR9565 + ?" line hints that my WiFi+Bluetooth Atheros hardware was New and Strange™ then, and https://wiki.freebsd.org/dev/ath_hal%284%29/AntennaDiversity (also 8 years old) led me to https://wiki.freebsd.org/dev/ath_hal%284%29/AntennaDiversityWhatChips (also... you get the picture) which doesn't even mention the hardware I have. At this point, I'm stumped. What are my options to get Bluetooth running on my laptop?
