It was done and it was rejected. Reason - there is separate file with
feature bits - userspace can decode them.

Please, post here the name of this secret file. :)

Here is an example from my test setup for the balloon:

Without deflate on OOM:
# cat /sys/devices/pci0000:00/0000:00:03.0/virtio0/features
0100000000000000000000000000110010000000000000000000000000000000

With deflate on OOM:
# cat /sys/devices/pci0000:00/0000:00:03.0/virtio0/features
0110000000000000000000000000110010000000000000000000000000000000

To decipher balloon bits are defined in include/uapi/linux/virtio_balloon.h
