Perfect. Thanks. Although she said a dot may need to be moved a stave-space away from its note, it typically looks wrong to me, and using only the spaces occupied by the chord is right. However, that's why we have \override directives...

One situation that apparently causes a "floating" dot is { d f fis }, assuming f and fis share a space. Since they are in the same staff position it seems appropriate for them to share a dot.

The case of dotted chords coinciding in multiple voices probably has to be treated separately. I think in that case the chords should move horizontally to allow their dots to live next to the appropriate note heads - but it is a different bug/feature.
