One reason is that most UIs send key events as they receive them from the 
keyboard, one at a time, whereas the curses UI gets a single key event from 
curses and then sends all of the scancodes which it takes to represent that 
key. In other words, a single key event from curses could result in as many as 
10 actual key events needing to be passed along - both the press and release 
for the actual key plus up to four modifiers (shift, control, alt, altgr).

Another reason is that it's not a problem for a lot of applications. I happened 
to hit it in an application, and, therefore, coded a fix for it.
