My personal opinion, but I'd rather see wider macOS support than Linux support, if it's a sheer matter of where time is allocated.
Linux already has world class package managers.

Supporting macOS Intel has been significantly harder, slower and more expensive for us the last few years than adding ARM Linux support. If it was easy and free we’d have kept it for longer (until Apple and GitHub killed theirs at least which is coming in less than a year).
That said, after trying Bazzite I now prefer CachyOS and Arch as a whole.
I can see the appeal of using Homebrew and Flatpak to keep OS updates a little more separate from app updates, although I don't really see a specific need for it for myself.
