Hi denis,
I have to say that I don't agree with you at all here.
The current state of this is just the same as the org-name attribute which is user editable in organisations without co-maintained resources.
It doesn't make sense to me to somehow give this country attribute more weight than the org-name attribute.
It also doesn't make sense to me to have different country code attributes for orgs with co-maintained resources compared to those without co-maintained resources.
If you think this is a problem I would say that the better solution here is to have a different org-type for organizations that have co-maintained resources.
That way we could communicate that some attributes are verified/maintained by the RIPE NCC for orgs with co-maintained resources.
Personally, I don't see how having country codes that are unverified for orgs without co-maintained resources is a real issue, but if people think that the mixing of verified and unverified data is an issue then I would propose the org-type solution.
