That seem to be the case, thank you! Digging a bit deeper, I now think that udev's README should be updated and initramfs-tools should somehow be tweaked: Interface naming rules go to initramfs only if the rule is named 70-persistent-net.rules, but udev's README suggests making a custom file with 75>prefix>80. Such rule would not get into initramfs as of current Debian testing.
