This is because the system necessarily has to use the IANA tz identifier
internally for compatibility purposes (e.g., across container
boundaries, or for other system configuration tools).

It's just a myth that the IANA tz identifiers are internal data
invisible to users.  Real systems do not work this way.  Changing that
will break interoperability.
