Great!
At least we are agree in some parts.
1. Not all users need it all the time (especially the new ones).
2. The Multiplier do exactly what you describe and much more. Multiply the selected object at desire distance on 3 axis, linearly or curve.
3. Could be better this plugin to have an entry in the right click menu but I wasn't able to do this (I'm not a programmer [:((] )

PS. It doesn't hurt you to take a look at Multiplier tread from start till the end.
Also you could try it and then remove it if you don't like it.
