Given that color and opacity are stored together, that would result in the 
same issue. But maybe just one new property textbox-backgound could be 
added. And the default would be completely transparent.
Thus it would not change the appearance of diagrams not having it.

That was not the point. If I only have one switch namely "draw background" 
how is it supposed to toggle four possible states?
 - only stroke, no fill
 - stroke and fill
both with or without drawing the text background?
