On another similar but different note, I don't think I've ever uploaded any code written by LLMs to GitHub, but I do sometimes upload fully complete projects under my "initial commit". Some people may legitimately just hide the edit history on purpose just because they don't want to "show their work". It's not really a particularly good habit, but I think a lot of us can relate.
A legit reason to hide your edit history is you might not remember what was in there. Say you have a moment of frustration and type out "this is an absolute garbage assignment by a braindead professor". Or you jot a quick note from the doctor because it happens to be open.
The simple fact is that the reader has no business reading the edit history, and the ability to make this happen should probably be far more prominent in document applications like Word or Google Docs.
