Would these processes be easier to perform, and to manage, if a change 
in a name record to undifferentiated (by recognition of identities while 
unable to create distinct forms of name), or from undifferentiated to 
differentiated (by removal of an identity to a new, unique form of name) 
was done by always creating new records, rather than altering an 
existing one?

It seems to me that, in strict logic, if a name authority record denotes 
a different identity, or a different combination of identities that 
cannot be distinguushed in form of entry, it should be a new record.
