Accept subclasses of occupation and sport

Currently this property has the property constraint (P2302) occupation (P106) sport cyclist (Q2309784). This constraint creates a warning if a subclass of sport cyclist (Q2309784) is used (for example road cyclist (Q52217314) or track cyclist (Q15117395)). IMO this is wrong and the constraint should accept not only sport cyclist (Q2309784) but also its subclasses.

The same applies to the constraint sport (P641) cycling (Q53121) (which should accept subclasses like cycle sport (Q2215841), road cycling (Q7339484), road bicycle racing (Q3609) or track cycling (Q221635)). Danysan1 (talk) 13:30, 17 December 2022 (UTC)
