If git's conflict resolution decides there are no conflicts, how would
such tool "ignore" that?

Can't such tool use "git checkout-index" for that?

 1. If git's algorithm decides there are no conflicts, and the new
    algorithm decides there are conflicts, how would such researcher
    find that out?

 2. Can't such researcher simply do:
    git -c mergetool.automerge=false mergetool?

Cheers.
