Pondering upon (the illusion of) different distros and its consequences - Thoughts?

I'm not even limiting it to how derivatives (i.e. Linux Mint, Manjaro, Nobara etc.) can completely (or at least by 99%) be realized by 'Ansibling' their parent distro (i.e. Arch, Debian Fedora etc).

Because, as it stands, there's not even a lot of difference between different independent distros. Simply, through Distrobox and/or Nix, I can get whatever package I want from whichever repository I want.

Most of the independent distros even offer multiple channels or release cycles to begin with; i.e Debian with Stable/Testing/Sid, Fedora with Rawhide/'Fedora'/CentOS Stream/RHEL etc.

So, while traditionally we at least had the package manager and release cycles as clear differentiators, it feels as if the lines have never been as blurry as we find them today.

Thankfully, we still have unique distros; e.g. NixOS, Bedrock etc. But I feel, as a community, we've not quite realized how homogeneous the fast majority of our distros can be defined (i.e. DE, release cycle, packages, script for additional configuration). And therefore miss opportunities in working together towards bigger goals instead of working on issues that have simply been caused by the (almost) imaginary lines that continue to divide different communities under false suppositions.
