Yes, and you could apply the DNS governance model to GNS. For example:

Let's say GNS gets traction. Users and implementation could provide a list of start zone mappings which are managed by ICANN and use this as a default. Effectively, this will give users global names. Just like now. .de will be managed by DENIC, .fr will be managed by AFNIC etc.

BUT: GNS is designed to allow to override such a setting. The ICANN root zone may be delegated by the user into the .icann namespace. So, locally, example.com in DNS would become example.com.icann in GNS. Alternatively, the user may also override ANY TLD mapping provided by the ICANN configuration - or individual domains - if needed. For example, if a domain is seized or otherwise censored in DNS.
