I think the problem is that .co.uk, .gov.uk and so on are very well known in the UK.

The .name subdomain rules are not very well known anywhere.

How familiar are you with Serbian co.rs, org.rs, in.rs (individuals) and top-level .rs too? Will you confuse it with iz.rs giving free subdomains to individuals too ("iz" means from in Serbian)?

How about all the other 200+ country TLDs and rules for non-country TLDs?
