Frame.backgroundColor => child.background :
I would rather agree with you, provided that

 1. axes do not become an exception: any uicontrol of any style set as
    child of a frame (if this is possible for other objects than axes)
    should inherit the frame's background as an axes will do. I don't
    think it is presently the case.

 2. there is a good clear reason to get the default background color of
    the frame's children from the frame, and only this property.
    Otherwise, the question will be the same for all other transferable
    properties:
    Handle of type "uicontrol" with properties:
    ===========================================
    Parent: Figure                              => Axes
    Children: []
    Style = frame
    BackgroundColor = [-1,-1,-1]                        background
    Border = "NoBorder"
    Constraints = "NoLayoutConstraint"
    Enable = "on"
    FontAngle = normal
    FontName = Tahoma                                   font_style
    FontSize = 13 font_size
    FontUnits = points                                   ~ fractional_font
    FontWeight = normal                                  font_style
    Icon = ""
    Layout = "none"
    Layout_options = "OptNoLayout"
    Margins = [0,0,0,0]
    Position = [20,40,40,20]
    Relief = default
    Scrollable = "off"
    String = []
    Tag =
    TooltipString = ""
    Units = pixels
    Userdata = []
    Visible = "on"
    HIDDEN frame PROPERTY:
    frame.foregroundColor                               foreground


For consistency, all these modifications would be needed. But is it so 
worth doing all that?
