The table should be in sync with the one from Xorg, 
/usr/share/X11/locale/en_US.UTF-8/Compose

There is a bug report on this, 
"Synch gdkkeysyms.h/gtkimcontextsimple.c with X.org 6.9/7.0"

A quick glance at the compose file of Xorg shows that these sequences exist there which is good.

If you would like to help with bug 321896 it would be great. The current state is on how to make the table much smaller, even with the addition of more keysyms. There is a script that converts en_US.UTF-8/Compose into a series of arrays that should be easy for GTK+ to work on. 
Regarding Greek polytonic there is an optimisation suggested by Tor to reduce the sequences (current about 1000 sequences out of 5000).
