It has been unmaintained since years, and there were only trivial or
tree-wide changes to the related files since many years, so the
code is likely very bitrotten and broken. For example the following
segfaults as soon as as you press a key:
qemu-system-x86_64 -usb -device usb-bt-dongle -bt hci -bt device:keyboard
Since we are not aware of anybody using bluetooth with the current
version of QEMU, let's mark the subsystem as deprecated, with a special
request for the users to write to the qemu-devel mailing list in case
they still use it (so we could revert the deprecation status in that
case).

The ``ivshmem'' device type is replaced by either the ``ivshmem-plain''
or ``ivshmem-doorbell`` device types.
+@subsection bluetooth (since 3.1)

+The bluetooth subsystem is unmaintained since many years and likely bitrotten
+quite a bit. It will be removed without replacement unless some users speaks
+up at the @email{qemu-devel@@nongnu.org} mailing list with information about
+their usecases.

@section System emulator machines
@subsection pc-0.10 and pc-0.11 (since 3.0)
the machines @code{n800} and @code{n810} have one HCI and all other
machines have none.
+Note: This option and the whole bluetooth subsystem is considered as deprecated.
+If you still use it, please send a mail to @email{qemu-devel@@nongnu.org} where
+you describe your usecase.
