/etc/debian_version has always been present in Ubuntu. It is as accurate as it ever was, it correctly documents the approximate Debian compatibility level of each Ubuntu release. But software should not be relying on its contents; third-party software should be using either /etc/os-release or the lsb-release command, both of which document the Ubuntu release information. There is zero need for an /etc/ubuntu- release.
