Thanks.  Two quick comments:

1. I'm happy leaving the key unbound by default -- in my own config, I
rebind "C-x n w" from widen to foldout-widen-to-current-fold and never
use the proposed "C-c @ C-w" bind.

2. "C-c @ C-x" already treats negative arguments specially ("...with
ARG < 0, -ARG folds are exited and text is left visible")
