No, that is precisely the code copied from the network script.

According to here, there always exists a green network: 
https://git.ipfire.org/?p=ipfire-2.x.git;a=blob;f=src/setup/networking.c;h=9dd5205e5a1cb60c4a0bb003ec2a8348848822f9;hb=refs/heads/next#l22
So we could just return True.

Just for the records

"I would prefer to give those function a “network_” prefix so that it 
becomes clear where this function is from and ideally shorten “is used” 
to just “have”. Like so: network_have_BLUE() and network_have_ORANGE().
" - "Re: [Patch RFC 04/15] network initscripts: check if the zone in the 
current config exists"

An ever moving target is hard to hit :-)
