I would say if the property has been unused for some time, nominate it for deletion and see whether there is consensus the property is not needed. I do not think there are any particular criteria.

Thanks Yaroslav, but ... you didn't answer my question ? :-)   What is the criteria typically used or kinda agreed upon for "unused properties" ?

Hi Thad,

properties can be proposed for deletion and, actually, get deleted.

However, when a property is approved there is usually a reasonable discussion showing the potential of its application. If it can be applied to multiple items it does not get approved.

Cheers
Yaroslav
