The gateway will not be inside any of the attached networks, so you have no route to it ?

Never attribute to malice what can adequately be explained by incompetence.

Well. Then it is maybe best to just error out on boot with a misconfigured network. Or revert back to the pre-14.1 behavior because of POLA.
I'll leave it up to you and will make sure I configure my interfaces with a netmask.
