If we look at Glasgow,
     https://www.wikidata.org/wiki/Q4093

the values for P31 in question are:

    Q515       -- city
    Q15060255  -- council area
    Q7309443   -- registration county
    Q202435    -- lieutenancy area of Scotland
    Q21457810  -- Scottish district (1975 to 1996)

Each of those statuses is different and independent (even in a purely Scottish context):  none of them implies any of the others, none of them is implied by any of the others.

So, in this case, I don't see that "city of Scotland" would help at all.

Why have instance of item and instance of superclass of that item?
If Glasgow is instance of : city of Scotland  and
City of Scotland is subclass of : city
Then we should not have Glasgow instance of : city

This principle should cut down a lot of these extra 'instances '

A big city is what? A city with more than a given number of inhabitants?
If so it is redundant because it can be inferred.

Criteria might be defined by local law and/or require some
administrative act. That's how it works in Italy, for instance.
