[Talk-GB] Are Northern Ireland, Wales & England 'states'?

[Dave F]

Hi
I'm unsure if Northern Ireland, Wales & England should be tagged as 
'states'.

A new user's changeset comment:
Adding more info. is_in:country_code was missing. Also classified 
Northern Ireland as a state so it appears in the same priority as Wales. 
Was unclassified before

Doesn't an admin boundary level cover it more accurately?

I also think the 'is_in:country_code' along with all 'is-_in' tags are 
redundant if there's a boundary tag..
