Upgrades to stretch keep the "eth0" style names.

Had to use google to search the wiki to find out what page you're
talking about here.

Here's when it was added:

<https://wiki.debian.org/NetworkConfiguration?action=diff&rev2=95&rev1=94>

For what it's worth, the Buster (not Stretch) release notes say:

  If your system was upgraded from an earlier release, and still uses
  the old-style network interface names that were deprecated with
  stretch (such as eth0 or wlan0), you should be aware that udev in
  buster no longer supports the mechanism of defining their names via
  /etc/udev/rules.d/70-persistent-net.rules. To avoid the danger of
  your machine losing networking after the upgrade to buster, it is
  recommended that you migrate in advance to the new naming scheme [...]

This is at
<https://www.debian.org/releases/buster/amd64/release-notes/ch-information.en.html#migrate-interface-names>
and includes steps to do this.
