I do wish it were that easy, but alas, no. What’s being asked for here is not a convenience feature that manages transparency values for you, it’s a method of blending that we simply can’t do.

Think of it like this:
X: Right to left
Y: Top to bottom
Z: Front to back

UI (2d) is basically X and Y, right?
So ZIndex is to adjust what overlaps what and is technically front to back.

That’s why it is called Z Index.
