Breakage caused by this was my main concern. I'm neutral on this either
way, I just wanted to know what the broader consensus was in terms of
how strictly to interpret "upstream".

I feel such a change would mostly impact proprietary tools. I've seen
some weird checks that rely on /etc/<distro>-release or perform generic
checks on the os-release file without really looking deeper. Which has
been fine in the latter case because 'rhel' was provided under CentOS.

An example of the former came up in the forums regarding the Abaqus
software by Dassault Systemes. It checks for a " 8\." pattern in the
redhat-release file during install to know which system it's on, which
wouldn't apply to Stream. Obviously removing the "\." would 'solve' this
scenario, but it's still not a clean or portable method across distros.
