Why these settings are deprecated?

[Tomasz Gąsior <mail tomaszgasior kao pl>]

I would like to ask question directly to main GTK developers. Why these 
Xsettings are deprecated?

* gtk-button-images
* gtk-enable-mnemonics
* gtk-icon-sizes
* gtk-menu-bar-accel
* gtk-menu-bar-popup-delay
* gtk-menu-images
* gtk-menu-popdown-delay
* gtk-menu-popup-delay
* gtk-show-input-method-menu
* gtk-show-unicode-menu
* gtk-toolbar-icon-size
* gtk-toolbar-style
* gtk-visible-focus
* gtk-alternative-button-order

What is the reason of limiting GTK customization? Why only application 
programmer should have ability to change these settings (as g-object 
properties etc.) and why user shouldn't?

And second question. Why you are forcing removing icons from images and 
menu items instead just disabling it by default in GNOME? Maintaining 
code of GtkImageMenuItem or images in buttons is too time-consuming?
(I know that programmer can pack image to button or menu item manually, 
but it is not the same. It isn't convenient and user have not ability to 
disable images added this way.)

Thanks for reply.
