Is there any work being done on the device authorization grant? Its a feature we would really like to have. <https://github.com/ory/hydra/issues/2416>

Not that I am aware of,
if you are interested Luke had an initial (very raw) draft
<https://github.com/lukestoward/fosite/tree/rfc8628-device-auth-grant>
It is also linked in the discussion.

I have an implementation I could contribute into fosite once my PAR PR is merged. Don't want to deal with commit conflicts
