Probably not.  Every source we rely upon is wrong in one way or
another.  And differing sources never agree completely.  So you might
move a node in a way that agrees-less with aerial imagery.  Try
another zoom level; the imagery probably won't agree with itself at
z-1.  Or check a GPX track; it'll be different again.

Again, probably not.  If you really don't want to move a node, you can
delete it and create a new one.  Or contact the mapper and see if
they'll agree to CT/ODbL :-)
