Didn’t he first [1] propose a variant in which using ‘git add -N’ was
not necessary?  The rule was something like this: consider each entry.
If it

 - matches HEAD, or
 - matches the work tree, or
 - is an intent-to-add

then we say it is easily recoverable.  If all index entries are
easily recoverable, then let the commit -a go through.
