Masstagger is useful when you want to apply a single value to multiple files, but you are unable to add a tag to a multivalue field across files, leaving the existing values intact.
What about the "Add value..." action?
Sure this does *add* values, but it's not very comfortable. To perform this action with the masstagger you need to click approx. 10 places and type the value manually.
My request suggests that you don't need to type anything that has already been typed once, and you are able to both add AND remove any value from a multivalue field.
