Yes this is true,
Had I known the upcoming changes in Unity 5, I would have designed it differently. However I have to port over a very big project from Unity 4 and, I have scripts predesigned with single FSMS in One Gameobject, that access components in other gameobjects. It's kind of buggered up all of my work, and redoing everything with new FSMs etc will take me forever. Thats why I think it would be beneficial to have the ability to copy a component and then simply paste it into the Target area of a 'set property' action.
I find it so much easier to follow up on scripts when I know that if I press this button, that thing fades and that other thing rotates etc...
Too many FSMS on one gameobject causes unneccessary clutter.
I'm aware that everyones workflow is different, and not everyone can get their own way, but gosh, this would literally be a godsend.
PLEASE CONSIDER IT
