Because that won't support existing practice.

Emacs defines C-xC-c in shell mode to be "interrupt-shell-subjob."  It is
defined to send a SIGINT to the process group.  Not a control-c, or DEL, or
whatever you have your interrupt character defined as.  Note that emacs
terminates the shell by sending it (I believe) a SIGTERM.  What keyboard
sequence generates that signal?
