The current policy is this.  If the device gets a gateway from anything
(either DHCP or the GUI or the ifcfg files) then it becomes a candidate
for the default route.  If you don't enter a gateway for any of that
device's IP addresses in the GUI, it shouldn't ever get the default

Yes, there's room for improvement.  If you check "Ignore automatically
provided routes" and you're using DHCP, NM should probably ignore the
gateway for that device when deciding which device gets the default

IPv6: target for next version
Alias: you can already add multiple IPs to an interface
bridging: planned
bonding: planned
VLANs: good to have, needs more investigation
