Yes I agree this is not breaking functionality, we have enhanced our network manager to use this feature to add another L3 segment and associate it back to the base Project Network (VLAN) thus extend the address range by 2x for that Project. If you are on say a standard /24 network and you max out the 254 hosts, our network manager adds another network (254 more hosts) to the project and extend the address range and associates back to the base network.
