In depth

Rotations transfer and translations do not, and that is the whole of it. Two rigs of different proportions share joint orientations and not bone lengths, so copying a translation puts the taller rig's limbs inside its own body. The root is the exception, because that is where locomotion lives — a walk whose root did not move would be a moonwalk.

What this does not do is retarget between different topologies: a rig with a split spine playing a clip from one with a single spine needs a decision about how to distribute the rotation, and that decision belongs to whoever knows what the character is. This matches by name, transfers what matches, and says what did not.
