Forget the healerstrike, let's talk portraits. Why is this feature still basically in beta?

When I change gear, my portrait should update to my current gear while retaining the lighting, pose, and other accoutrements I've set. It should do this automatically without my having to go in and re-save everything.

OR

It should allow the other option to select "just leave it as I set it" and no matter what gear changes I make, my portrait remains unchanged from how I made it.

Why isn't this a thing? Why can't it be a thing? Are you as annoyed as I am, and what can we do about it?
