Yeah, it's unclear to me at the time if the dialogue box in the screenshot appeared when doing a select all operation, but it reads as though the OP dev didn't understand git, discarded their work, and got upset that it was an option.

Realistically if the dialogue box appeared, I'm not sure there would be anything else the IDE could do to prevent the dev from themselves. Perhaps reject operations affecting 5000 files? But then you'll just have someone with the same issue for 4000 files.

The issue I linked has a very good analysis of the UX issues and several suggestions for fixing these. They went with a minor iteration on the original message box, which not only includes a clearer message and the number of files affected, but also defaults to not touching untracked files (while preserving the option to delete untracked files as before).
