C-w doesn't work the same. In bash it will delete the word before the cursor. In Emacs it will cut selection (which is always there, just sometimes invisible and then C-w does unpredictable things).
And then there's the experience of using Jupyter's terminals, where you reflexively C-w to delete the last word, but the tab closes. You then reopen the terminal, which has helpfully retained its state--including the word you just tried to delete.
