I do not particularly think it is "dangerous".  In fact, that sort
of behaviour was what I had in mind when I said "work sensibly".

When resolving a conflict that they added a new path at stage #3 to
remove that path, I can say "git rm $that_path", which removes all
stages of that path and make the index closer to the next commit.
Or I may decide to keep that path by "git add $that_path", which
adds that path at stage #0.  I think "git mv $that_path $over_there"
that drops that path at stage #3 to stage #0 of another path would
be in line with these two.
