Oh hi there @tabrisnet 
Check, that is same for the deprecation, both architecture are affected (because of Supervised being deprecated).
Using Armbian to run a Supervised installation method is not supported by the Home Assistant project (and documented as such). Thus you already run an unsupported/community-supported installation. You’ll remain unsupported moving forward, just like today.
You say you’re removing the docs for this, but implying that Supervised will still exist. Also that there will be a repair added for us. Can you please say which “official documentation” will be changed and which will not?
Home Assistant Supervised, as an installation method documented and supported by the Home Assistant project, will cease to exist. You can choose to run it that way, but it means you are on your own / community-supported. Which is already the case for your setup today.
