This is probably true, because Java programmers have limited tools
for software reuse:  Inheritance and explicit subroutine calls.  If they
had the ability to connect methods directly using CMBs, the source
base would look different.  There would be less cut-and-paste.  A true
mechanical analysis of the applicability of CMBs to connect methods
would have to disregard lots of hand-crafted of method calls, and
unwind uses of inheritance where delegation (had it been available
at the time) would have been a better choice.
