Exactly!

One record will point out a person (as an example). A person have a 
lifetime of say 120 years. We need to find a handle which can have 
the unique identifier for at least 120 years.

That is not the case with email addresses.

Email address might be one of the attributes in that person object.

Se the RPSL specification. You have to be conformant with that 
regarding lots of semantics. Don't reinvent too much.
