This is a bad move. More than ever we need Linux standards and this goes in the opposite direction. It would be OK for SUSE to support btrfs as a first class choice of filesystem but the extfs family should be the standard one.
And ZFS works just fine on Linux. If people want to use it, then the distros should not put roadblocks in their way and that means, ZFS should also be supported as a first class choice for servers.
Note that "support" is different from licensing and from "included in our install repo". It is OK to have different licensing for things like this and to install it from a non-distro repo. Look at PostgreSQL for an example of how you can install a mission critical tool from a distro-compatible repo that is run by the upstream project, in this case, PostgreSQL.
But even though it comes from a different repo, it should be "supported" by the distro to the extent that they make a best effort to help people resolve problems. It doesn't mean that you need to be experts in every nuance of the tool and the best way to do that is to maintain a good working relationship with these upstream projects.
Something like ZFS or PostgreSQL are mission critical tools that use Linux as the interface to the hardware, My comments do not apply to any random app or utility that someone wrote for Linux. Perhaps btrfs belongs in this class but I personally don't know since I have not used it.
Most of the things by freedesktop.org in the last.. idk 5-10 years. Console-kit/logind, AppData, dbus being used for the lower parts of user-space, and probably many more that i don't recall now. Oh, and pulseaudio.
