The moniker for that is "predictable interface names". And you seem to assume that there hasn't been a discussion. This being Debian, there sure has been one, you just didn't notice :-) The default (Debian /has/ to settle for one default, since many people installing Debian don't know or care what an interface name is, let alone what the heck a /predictable interface name/ is), is "predictable interface names". Since not everyone wants or likes that default, you can override it: just just add net.ifnames=0 to your linux commandline (e.g. in /etc/default/grub, like so [1]: GRUB_CMDLINE_LINUX_DEFAULT="net.ifnames=0" don't forget to run update-grub afterwards, ask here if unsure, proceed with care, etc. etc.).
