The main problem is this one introduced in 2/5 which needs get ack from maintainer.
For me, I would suggest to make sensor_specs transparent to user if
it's really not needed by users.
Please try to make it either optional or hide to core users as well.
And I guess the later one is doable after a glance at the core code.
