This property on items for fictitious subjects

user:Pigsonthewing has twice removed this property from the items for fictitious vehicles, with the rationale that this should not be used on fictitious entities. However, the property was proposed with examples including fictitious vehicles and I see no reason at all that they should be not be included, although any issued by qualifier would likely be the author/screenwriter/film company/etc of the work in which it appears. I'm starting this section to determine whether the implied consensus of the property proposal discussion does hold. Thryduulf (talk: local | en.wp | en.wikt) 21:21, 10 June 2016 (UTC)

There is no reason why the property should not be used in fictional items. In fact, as you point out, the proposal included those explicitly. --Srittau (talk) 13:23, 11 June 2016 (UTC)

Poppycock. Also, do you have a citation confirming that the (very real) Illinois Department of Transportation issued a licence to a fictitious vehicle? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:32, 4 July 2016 (UTC)

You are conflating two separate items here - whether fictional items in general can be used with this property (clearly yes) and whether the qualifier on one specific use of this property is correct - this helps nobody. Thryduulf (talk) 12:11, 4 July 2016 (UTC)

There are indeed two separate issues, but no, I am not conflating them; hence my use of the word "also". Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 19:23, 5 July 2016 (UTC)

So what is the reason for asserting mine and/or Srittau's statements to be "Poppycock"? As the proposed I can safely say that it was my intention that this property be usable on both real and fictional items and was under the impression that as this is the normal state of affairs (to my knowledge anyway) and by including examples of both in the property proposal that this was made clear at the time.
