Lots and lots of times, and i have both Terminal(SSH&Web in UI), + Samba + File-Editor Add-ons ( ones had Visual, but i found to to crappy ), i prefer “simple” file-editors, i.e NPP in windows, But most in HA i do in the GUI/file-editor , So Yes i prefer HAOS, and have no need for HA in Docker … i went for Supervisor from first install, my own decision ( For simplicity ), first Supervised in Debian, but it was “to fragile” for my curiosity.
You get the answer you get to your question, bc of your way to “speak” about and to people you don’t know and you have no idea of how they think, why and what they do and or try to i.e help or create something for others to “play with” , Most People does not come to this forum to listen to your Problems, but many are willing to help or advice People here
I.E The Internal Team(in your words) first i thought you mend The International, but never mind, They Don’t actually have a User-Base (Some might see it that way now thou) They started with something, for them self, other people joined in, some more wanted to add-in, hardly anyone did it to “Serve” someone else ( Like i.e You )
They Had a vision, it grew, and new ideas/options turned up, and it grew more , some “found” their “Work” in Github (sounds familiar ? ) They download it and found it cool.
Now this was quite some years ago, as you know, now there are tons of users, And again Contributors, “internal” integrations, 3rd part of same, Official add-ons, and Community of same … Options are endless for the endless stream of users with their own ideas.
But You are stucked in your own “container” and insulting people who don’t agree to your BS , Install your ADD-ON of choice in a Container(next to HA, or under would be the right term) Then write a Guide/Tutorial, for other People, so they don’t end up in Your situation
It’s clearly stated in the DOC’s NO Support for Add-Ons, and not many of the users in this Forum are running Container so there haven’t been a stream of “requests” for a “Dummy” for this, People running Container, most likely choosed this for a specific purpose and with required knowledge, a few bc they think it was/is cool, with that decision they rejected the Benefit of Supervisor, Or thought they could live without it ( which 99,9% does )
Your best choice is Google, there are people there have dedicated their time to produce Tutorials for You
