On TTY frames, they are the only information available about the
composition (because the actual composition is done by the terminal
emulator).  On GUI frames, we have more important information already
shown.

If someone wants or needs to know which characters participated in a
composition on a GUI frame, they can go to those characters in the
*Help* buffer and type "C-u C-x =".

That said, if someone wants to work on adding the character names to
the GUI display as well, I won't object.
