Click buttons in the IDE to add source control.
IDE says a bunch of files have been changed.
But I don't want to make changes to the files, I want to source control them.
Attempt to undo the changes. Click "discard changes" thinking it will put them back to how they were before clicking add source control. Get a warning dialog that this is not undoable, but that's fine because I don't want whatever changes it made to my files anyway.
All files are deleted and unrecoverable.

Like that experience sucks balls and it's reasonable that a person wouldn't expect "discard" == "delete". Also, from reading the GitHub thread, apparently at that time VSCode was doing a git clean when you clicked this. Which like...yeah why the hell would it do that lol? I don't think I have ever used git clean in my entire career.
