What's the current status of btrfs support in Gnome and related

I'm a bit worried that relevant application do not properly support
btrfs and we take a step backwards and force the novice end to the
terminal to deal with various filesystem related stuff if we switch to
btrfs by default ( as opposed to make the switch when the proper support
is in relevant applications ).
Personally I have yet to see what benefits btrfs brings the novices end
user over other filesystems that warrants us to switch to it by default.
The first question to answer here would be what 'proper' support would
mean. It is certainly supported as a 'plain old filesystem' ie you can
format your partition as btrfs partition, and the desktop will be able
to use them just like any other filesystem. Which is probably good
enough for the initial rollout.
But of course, we are hoping to gain some exiting new functionality by
switching to btrfs. Some use cases I can think of off the top of my head
* New disk.
I plug in a new disk, I get a notification that tells me:
You just plugged in a new disk, do you want to use this to
( ) backup your current disk
(*) use it as extra space
[Ignore this disk for now][Go ahead and do it!]
This would uses btrfs in so far as it can just expand the filesystem
over multiple disks. The backup part would possibly involve snapshots.
* A file locker.
Create a 'Private' or 'Locker' folder in the home directory and
encrypt the tree below that. Then we can make meaningful UI that
tells people to store confidential stuff below that directory. And
we avoid the need to ask for a password halfway through boot, when
can't really do these kinds of interactions without lots of
contortions and when we can't really have good i18n, etc.
This would use btrfs encryption capabilities (if it has those, I don't
