Why keeping this property?

This property isn't used in any item (except for a non-notable one created just upon the proposal), and its source seems to be discontinued. How should it be used? Is it useful at all?

Pinging the creator So9q and the property supporters: @ChristianKl, Salgo60, 轻语者: Horcrux (talk) 16:45, 13 May 2024 (UTC)

There have been no usage in 4 years so just propose the property for deletion. If the property proposer still claim the property is useful let them prove it by populating it, no point in asking for opinions. Infrastruktur (talk) 18:27, 13 May 2024 (UTC)

I agree, having a discussion about whether there should be a discussion to delete it is unnecessary. Just go ahead and propose it for deletion. ChristianKl ❪✉❫ 20:51, 13 May 2024 (UTC)

There are probably more like this that should be deleted. Properties proposed willy-nilly and then discarded _should_ be deleted within a reasonable timeframe, I would say one year is pretty reasonable. Infrastruktur (talk) 18:51, 13 May 2024 (UTC)

• Thank you for the response. I've opened a deletion proposal: Wikidata:Properties for deletion/P8409. --Horcrux (talk) 14:46, 16 May 2024 (UTC)
