I agree to this issue, I assume that without such function the concept of
face recognition is rather useless for anything more than a few images.

One more question that just came up in this context: In my people tree
(digikam 5.9), I see both an 'Unknown' and 'Unconfirmed' tag. Not sure
whether 'Unconfirmed' is a legacy entry or whether it serves any purpose?

Logically, with my limited English skill, 'Unconfirmed' would be the faces
that are not known to the algorithm and should be confirmed by the user.
'Unknown' are people that are confirmed not known, I.e. strangers, and be
excluded from the AI learning in future runs. But as of 5.9, digikam places
newly detected, unidentified faces into 'Unknown".

Forgive me please if this has changed significantly in 6.0, I haven't had
the chance yet to test it since I like to stay with distro versions where
possible.
