This should explain more of what wikidata is capable of doing via 1 tag:

Stewart I do agree that the tag "is_in" is completely useless, I was more
targeting the sub-tags(I put a star not to list them, but I will)
For example Ottawa:

name: Ottawa
is_in:continent: North America
is_in:iso_3166_2: CA-ON
is_in:country: Canada
is_in:country_code: CA
is_in:state: Ontario
is_in:state_code: ON

state_code,country_code, iso_3166_2 are ISO notations that can be used and
have a standard that is international and can be parsed easily by computers.

What I don't like in "is_in" tag is as you said it's a bunch of garbage
thrown together, which helps no one:
is_in:capital_cities; Australian Capital Territory; ACT; Australia
is_in:state=Australian Capital Territory
is_in:country=Australia (use english name of the country)
