I'm already seeing discussions on the mise[0] Github discussions about Omarchy specific changes and designs. I'm not saying anything about these specific changes and they seem mostly distro-agnostic for now, but it goes to show how it can affect other distros/software even if you don't use it.
[0] mise is being sponsored by the Omacon foundation, which is what all this money is technically going to. It also happens to be the only "independent" tool being sponsored by the foundation, as the hyperland dev is essentially contracted by them and the QuickShell dev was hired by DHH.
