RedHat 7.4 Release Notes: "Btrfs has been deprecated" - wut?

[Brendan Hide <brendan@swiftspirit.co.za>]

The title seems alarmist to me - and I suspect it is going to be 
misconstrued. :-/

 From the release notes at 
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.4_Release_Notes/chap-Red_Hat_Enterprise_Linux-7.4_Release_Notes-Deprecated_Functionality.html

"Btrfs has been deprecated

The Btrfs file system has been in Technology Preview state since the 
initial release of Red Hat Enterprise Linux 6. Red Hat will not be 
moving Btrfs to a fully supported feature and it will be removed in a 
future major release of Red Hat Enterprise Linux.

The Btrfs file system did receive numerous updates from the upstream in 
Red Hat Enterprise Linux 7.4 and will remain available in the Red Hat 
Enterprise Linux 7 series. However, this is the last planned update to 
this feature.

Red Hat will continue to invest in future technologies to address the 
use cases of our customers, specifically those related to snapshots, 
compression, NVRAM, and ease of use. We encourage feedback through your 
Red Hat representative on features and requirements you have for file 
systems and storage technology."
