Q1: How would encryption of /home and / subvolumes be implemented?
A1: For the F33 timeline, we plan to stick with Btrfs-on-LUKS, so there will be one big LUKS partition, on top of which there will a Btrfs with multiple subvolumes (root and home). In future, once Btrfs implements native encryption (this is work in progress upstream), we will propose to make a switch, but this is definitely not going to happen in F33.

Comment2: Well, technically it does not change from today's configuration. Today, if you select encryption, it will create LUKS. If not, it will just use ext4-on-LVM-without-LUKS. But I see the point, will make the update.
Are subvolumes really mostly like directories?
In this section, there is a phrase "But subvolumes share most of the other trees". What does that mean? What are trees in this context?
does Red Hat's dropping of BTRFS suggest problems?
