I use BTRFS on a number of Fedora systems. It doesn't seem to be very different from extx, mostly because I don't use any of its new features.

Possibly ZFS-adjacent but without the nightmarish license problems?
There are no nightmarish license problems with ZFS.
There's an issue where the license isn't GPLv2 compatible, but they're quite similar in spirit.
As a user, it has no impact on me and works great.
If your distro complies with the GPL and the Sun / Oracle ZFS License, there is a problem. Ubuntu seems to disregard this.
Most dev work for ZFS is now done on Linux as I understand it - no longer a second-class citizen on our favourite platform.
As I understand it, this is true of the open source fork of ZFS. Oracle continues to develop a closed source version but none of that code is open. As I understand it, the memory management of ZFS doesn't mesh perfectly with the Linux kernel. A legacy of its Solaris origin.
Am I missing something? It's in the kernel, but if it was that good, lots of distros would be defaulting to it ... and they're not.
Yeah, in fact, RedHat has removed it as of RHEL 8:

Yes. Kind of scary. But Fedora uses it as the default so that is probably the future for RHEL.
