GtkTreeView keyboard binding are not intituive

Status in gtk+3.0 package in Ubuntu:
Most GUIs, like MacOS X, Microsoft Windows and Qt handle the keyboard bindings
for its treeviews in the same way: user can easily expand, collapse and move
into tree nodes using only the arrow keys.
In Gtk+, however, is quite different. User needs to press "plus" and "minus"
key to collapse and expand nodes, leaving Right and Left arrows with
essentially null functionality. Well yeah, that keys allow to move
into row cells.
Seeing many of the applications written using Gtk+, there are not many cases
where user find useful moving horizontally across the row with the keyboard,
most GtkTreeView that I see are simple and used only to show information.
So I guess the current GtkTreeView behaviour is crazy, not useful in most
cases, goes against intuition and against good User Experience.
I'm really not familiar with Gtk+ programming but, as user, I find this "bug"
extremely annoying in my day to day.
So, I make some changes in Gtk+ to enhance (from my point of view) the
of GtkTreeView with the keyboard.
The attached patch to the 3.4 branch modifies the default GtkTreeView
with the keyboard, expanding nodes with the right arrow and collapsing it with
left arrow, selecting parent and child nodes when appropriate:
- When user press Left on a collapsed node, Gtk+ select the parent node.
- When user press right on an expanded node, Gtk+ select the first child
Users that want to navigate into cells horizontally (as I can see, a non
frecuent use case) will need to press Ctrl+<Left|Right>. Users can still move
to the parent node with the Backspace key, without collapsing anything.
I don't know exactly if this behavior change break some expected behavior to
application programmer, I hope not.
A last question, Why Gtk+ programmers implemented the current GtkTreeView
knowing the big difference with other tested GUIs?
