Here is the deal: You cannot "grandfather" a newly created privilege to a select population--a population that never received the privilege before--if for no other reason than the privilege did not exist in the past. The grandfather bit is not only a connection to the origin of the term but also a hint about proper usage: people in the past (grandma could not vote) must have been able to and did enjoy the privilege at some point in the past. I did not want to come off like a strict scrutiny word maven (synonym: dickhead) when I wrote my first comment because it would obscure the larger point: "grandfathered clauses" have negative connotations for new/potential customers. My goal was to be helpful and not to strut my lexicographic tail feathers.
