does this flag specify squashing the last N (N=layer-count) layers? If so I suggest renaming it to last-n-layer.
Or rename it to from-layer, meaning squashing all layers starting from from-layer (and --from-layer=0 means squash all layers)

nit: maybe use something like author="nerdctl" and message="generated by nerdctl squash" as default values.
