Terminology nit: the purpose of a registrar is to allow folks the freedom to choose the service level/price that meets 
their needs. I assume you mean 'registry'.

An alternative viewpoint is that the parent zone is responsible for the child zone, thus the parent registry can impose 
what they feel are appropriate requirements to ensure the zones within that registry are maintained correctly. If you 
do not agree with these requirements, there are now over 200 other registries to choose from (and soon to be many, many 
more).
