And THAT is the problem.
That would depend on whether they're being *used* on systems that have interfaces with the newer names. If so, report as a bug. However, if you upgraded to stretch, I think you'd have to show that you'd allowed the system to preserve the old names, rather than trying to circumvent Debian's methods for doing so.

Who added this line??? I expect you did, indirectly. It all depends on the conversation you had whenever Grub was upgraded (eg, Nov 2018) as Grub attempted to preserve changes made to /etc/default/grub. Do you have any other files matching /etc/default/grub* ? After all, you just wrote: "but I changed to the new names" so it looks as if Grub succeeded in hanging on to that change. I think you're meant to live with the old names if you were upgrading, unless you know more that the wiki writer who wrote: "Upgrades to Stretch will retain the old device names - despite what you will read on the web - removing /etc/udev/rules.d/70-local-persistent-net.rules will not give you the new names even if followed with a update-initramfs -u and update-grub. ( have not yet found the correct Debian incantations for this yet?? )" Cheers, David.
