I think the new TextInputClient interface would be useful not only for Metro TSF
but also for ui::InputMethod IMEs to implement "delete surrounding text" like
feature, right?

If that's correct, file a bug like "Add delete surrounging text feature to
ui::InputMethodIBus" on crbug.com, assign it someone in your team, and add the
crbug.com bug # here.
