Ah, these things always appear simple until you think about them a bit more.
A wild guess but maybe this design is in anticipation that there will be
another value.
Visible
Collapsed
*Invisible*
Collapsed and invisible aren't the same (e.g. An invisible cardboard box and
a collapsed one are different. The invisible one still takes up the same
space as the visible one while the collapsed one doesn't take up any space).
This illustrates my point.
<StackPanel>
<Button x:Name="btn1" Content="Hello World"/>
<Button x:Name="btn2" Content="Hello World 2" Visibility="Collapsed"
/>
<Button x:Name="btn3" Content="Hello World 3" Opacity="0"/>
<Button x:Name="btn4" Content="Hello World 4"/>
</StackPanel>
btn2 takes up no space as it is collapsed while btn3 is invisible but still
takes up space.
So at the moment Invisible can be achieved by setting the Opacity to 0 but
in the future they may add another value to the enum for this.
