The AlmaLinux project has announced
that the upcoming 10.1 release will include support for
Btrfs:

Btrfs support encompasses both kernel and userspace enablement, and
it is now possible to install AlmaLinux OS with a Btrfs filesystem
from the very beginning. Initial enablement was scoped to the
installer and storage management stack, and broader support within the
AlmaLinux software collection for Btrfs features is forthcoming.

Btrfs support in AlmaLinux OS did not happen in isolation. This was
proposed and scoped in RFC 0005, and has been built upon prior efforts
by the Fedora
Btrfs SIG in Fedora Linux and the CentOS Hyperscale SIG
in CentOS Stream.

AlmaLinuxÿOS is designed to be binary compatible with Red Hat
Enterprise Linux (RHEL); Btrfs, however, has never been supported in
RHEL. A technology preview of Btrfs in RHELÿ6 and 7 ended with the
filesystem being dropped from RHELÿ8 and
onward. AlmaLinuxÿOSÿ10.1 is currently
in beta.
