Short answer: I don't think so.

Longer answer: I found some info on the layers in the unit tests:

function layer = create_layer(count)
    c = get(0);c.usedeprecatedskin = "off"
    f = figure("dockable", "off" ,"infobar_visible", "off", "toolbar_visible", "off", "menubar_visible", "off", "layout", "border")
    f.figure_size = [300, 300];

    //layer
    layer = uicontrol(f, "style", "layer", "constraints", createConstraints("border", "center"));

    for i = 1:count
        fr1 = uicontrol(layer, "style", "frame");
        fr1.layout_options = createLayoutOptions("border", [10, 10]);
        fr1.layout = "border";
        uicontrol(fr1, "string", "button " + string(i) + "1", "constraints", createConstraints("border", "top"));
        uicontrol(fr1, "string", "button " + string(i) + "2", "constraints", createConstraints("border", "left"));
        uicontrol(fr1, "string", "button " + string(i) + "3", "constraints", createConstraints("border", "center"));
        uicontrol(fr1, "string", "button " + string(i) + "4", "constraints", createConstraints("border", "bottom"));
        uicontrol(fr1, "string", "button " + string(i) + "5", "constraints", createConstraints("border", "right"));
    end
endfunction


What you can do with this function:

ll=createlayer(3).

ll.value=1; //figure shows the 4 buttons you put in the 1st layer
ll.value=2; // now figure shows the 4 buttons you put in the 2nd layer
ll.value=3; // now figure shows the 4 buttons you put in the 3rd layer


This is how I understand the usage of such layer uicontrol: use a layer for each user interface you want (like one with a graph taking up all the figure size, one with parameter boxes, one with loading data infos, ...) then use the layer.value=i to show quickly the ith bit of the interface you want.
 If I'm correct, this is just like a tab uicontrol, minus the tab at the top!
