We use this similar logic throughout a lot of our scripts for determining the external facing IP address in a portable manner, it's just that the init.d scripts are a bit more strict about it. This is the equivalent of using the name defined in the slaves/masters/tracers/etc. files to determine which port to report as.
Switching to a system that depends on DNS to succeed will fail for all first time users, which is a penalty that will not be worth it. If someone can find a better way to determine outward facing IP address I would love to have it, but unfortunately networks are hard.
