#3Ahahaha, I love this! I love how this new fandango thing harkens back to the earliest days of MS-DOS when it ran on a 086 or 286, back in the early (very early) 90s.
Have to respect MS' backwards compatibility fanaticism. Impossibly as if a native port of MS Teams would be created for MS-DOS 3.1 (hahahaha). When more plausibly the MS Teams servers run on an ancient crazy proprietary MS-DOS 3.1 mainframe (still implausible, but hey).
I know that this device name restriction also applies to Windows file names, so it's not that surprising (if you are inclined to be less fun than possible), but if you like fun, you can pretend the former.

#5Does this imply it's writing a file to the fs for its internal storage, with the name matching the channel's name instead of a channel ID?

I was about to say "Which is essentially leaking the existence of something terrible inside. They should be embarrassed to say something like this in public. Like saying you can't have %s or $PS1. Why the hell not? What are you doing with this user-supplied input?"
But maybe it's more about what everyone else might do with a channel name. Ie they might cut & paste it anywhere, and I guess windows users aren't expected to escape their own strings when pasted into cmd or powershell or wsl.

#10This is most likely due to those names not being allowed for files or folders in the Windows file system. MS Teams channels create a matching folder in SharePoint where file attachments are stored.
