There are other similar omissions, e.g. you can state Preferredness of an identifier but not Title nor Image.

There are P81b, P82b (end of inner/outer bounds) that apply to Time-Span that applies to any Period/Event.
However, there are no standard types to state "Period of use/existence/activity of something", such as:
- use of an Appellation or Title
- life of a Person
- floruit of a Person
- period of group membership or profession of a Person (e.g. reign)

You absolutely count as one of the thesaurus people :-)
So: the idea was considered seriously, but not adopted.
