Give the ability to recognize a person by fingerprint and assign a different automation or scene to each finger.
When my wife came and unlocked the lock with her finger, I get a notification that she came, if one of the children came, I will know which one.
It is also possible to add unlocking with different fingerprints and activate different scenarios. If I came home and in a good mood, I unlock for example with my thumb, bright light and TV or music is turned on, if I am in a romantic mood and want to surprise a girl, another scenario is turned on, I use my other finger.
Please expand the functions of Aqara lock u200🙏🏻.
Thank you for sharing your share! 
We’ve found it challenging to implement this functionality within Matter, as the protocol currently does not support fingerprint-related automation.
However, we are planning to introduce similar automation conditions in Aqara Home to achieve the scenario you described.
While we currently cannot commit to a timeline, we are continuously enhancing the capabilities of our Matter locks!
Very strange 
Aqara D200 lock has this function!
Does each lock have a different matter protocol.
Somehow it is more believable that on purpose was programmatically reduced functionality((
I really hope I am wrong, and Aqara did not go the way of hard marketing “You want more features - change every time for a new one”, and the lock has not even a year))).
Again, I hope I’m wrong and soon we will see additional features )))
