Purpose of this property

Apart from being the inverse of owned by (P127) (which was the sole rationale stated in the proposal), does this property actually provide any kind of value? Take a look at Q513666#P1830 for example, ownership is should be already modelled in the objects and huge lists like that make items difficult to maintain. Nw520 (talk) 14:17, 26 November 2022 (UTC)

• Take a look if you would at Q116809558. The almost-forgotten person is remembered (mostly) as the owner of a cult painting (Q4247398). And, inversely, the fact of ownership is almost non-notable in the context of the painting itself. Retired electrician (talk) 14:18, 17 February 2023 (UTC)
