Hospital 1F3E5 - must this property restrict subclass of(P279) items?

After I put this property with value "1F3E5" in the hospital (Q16917) item it gives me an error that hospital (Q16917) is not an instance of something. This is the general idea of a hospital and not a specific one, so in those cases we usually don't use 'instance of'

• unicode.org: https://unicode.org/cldr/utility/character.jsp?a=1F3E5

Emojis/unicode characters also usually refer to general ideas and not specific ones. It's in the case of specific emojis/symbols like ie. the Tokyo Tower (Q183536) which is a specific one and the tower itself is an instance of an observation tower (Q1440300). Now a subclass of (P279) an observation tower (Q1440300) might be ie. a gyro tower (Q13405507) What is your opinion? Should this property continue giving errors for items which are subclass of (P279) but lack an instance of (P31) which use this property? Seeitinmusic (talk) 12:43, 10 November 2019 (UTC)
