The same applies to *all* link-local IPv6 addresses as well as link-local IPv4 addresses.
The same applies for all alternative names for localhost:
For example on Fedora:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
People even use FQDNs for their localhost address to test their stuff without network connection.
