These are different cases. The arts_centre is performance/exhibition oriented and might have a small overlap with community_centre.
The youth_centre is a 100% subclass of community_centre, a place where a particular target group meets on a daily to weekly basis.

Such "What if" questions appear rather hypothetical to me unless you have real examples where there would be a conflict.
