From what I gathered, there are two things that might need to be
reimplemented on Abiword so it's on par with GTK+ widgets wrt touch
friendliness,

* touch/kinetic scrolling: This is implemented in GtkScrolledWindow
through 3.0's GtkWidget::captured-event, as Abiword doesn't use this
widget for scrolling support, this piece of code has to be reimplemented

* text selection, in that branch, there's a private GtkTextHandle helper
object that text widgets use to manipulate the selection, if it remains
private API, Abiword could need its own copy of it.
