However this is against with the default behavior of service files on OpenWrt.
People who want to use it should enable it by themselves.

It can be a optional feature, when someone packed it into a firmware, and share the firmware to others, you know, not everyone need it.
Also, it requires a available network connection when setting firewall rules, which is almost impossible at the first run, that I mean, when someone flashes a new firmware for their router, they actually needs to setup the network firstly before running it.

Your configurations won't be lost when you're doing a upgrade (unless you have selected "don't keep configurations" manually), so it's fine to disable it by default.
