I messaged support about this at the end of 2020, they just now followed up 8 months later that they “received a reply from the Escalation team that the Experts team has confirmed that the fix for this bug will be implemented in the future without any specific ETA”. So I think the devs finally have it tucked away in a to-do list. But as of Aug.25 2021, it appears that other biometrics other than fingerprint are still not supported. I already switched password managers, but I hope this info helps someone!
