This is the downside of the free tagging system! It makes no sense having both tags - indeed this should be thrown as an error in the editors (what happens if the value differs between these tags?!).
But as you found out, as soon as you propose a (relatively simple) edit then one individual can block it. A compromise is to adjust the code to accept both and have validation on cases where both tags are present. I understand this to be "easy" for data consumers but in reality it is not "easy" because it's taken you years to discover this edge case (consumers shouldn't have to spend hours digging around the intricacies of such basic data).
