Here is my newest test. The backports provide a 4.5 kernel:
####
kernel: 4.5.0-0.bpo.1-amd64
btrfs-tools: 4.4-1~bpo8+1
####
This time the raid1 is automatically unmounted after I unplug the device and it
can not be mounted while the device is missing. See below.

As I said before, I consider this problem is not
caused by Btrfs, but by hardware.
Please see the following comments.

When you turned on Fantec case, four disks, WD20(sdf), WD75(sdg),
WD50(sgh), and SP2504C(sgi) were attached. It's a matter of course.

After hot-unplugging WD75(sdg), surprisingly, other three online
disks, in other word, not-unplugged disks, were re-attached.
From the filesystem's point of view, once its *all* backend
devices suddenly became missing. In this case, I guess,
any filesystems can't work correctly.

In fact, we can see some problems happened not only on
Btrfs but also on ext4 on WD20(sdf1). ext4 was remounted
here and was recovered from some inconsistent state.
Probably similar problems happen on any other filesystems,
for example XFS.
Apparently it's not what you intended. You just tried to
hot-unplug a disk to confirm whether Btrfs's RAID1 works
correctly or not. However, what happened here was that
all four disks were detached and tree of them were
attached again.

Furthermore, device names for Btrfs were changed. WD75 was
from sdh to sdg and SP2504C was from sdi to sdh. It would
make things worse.

This time the raid1 is in state "unmounted" after removing the device. This is
different to what I found with kernel 4.4.

Then all four devices, WD20(sdf), WD75(sdg), WD50(sdh),
and SP2504C(sdi) were attached. Attaching WD75(sdg) is OK.
However, re-attaching already-online devices WD20(sdf),
WD50(sdh), and SP2504C(sdi) are apparently strange.

There were some problems on ext4 on WD20(sdf1) again.
