I think we have to be careful with the stats' interpretations because
they often express what we want them to.
Real life code-bases are rarely the ones we choose carefully for our statistics.
There's often a lack of coding conventions and many duplications (with
different coding styles), that's why I suggest to activate this
feature with an option depending of programmers' judgments.

Of course, inter-file common trivial shapes would be rather
straightforward and probably would also bring some good results on
quite a lot of code-bases as discussed previously.
