We should also take into account optimisim about future improvements in
tooling.

This is trivial:
case 1:
this();
+ fallthrough;
case 2:
that();
But what we inevitably get is changes like this:
case 3:
this();
+ break;
case 4:
hmmm();
Why? Mainly to silence the compiler. Also because the patch author argued
successfully that they had found a theoretical bug, often in mature code.
But is anyone keeping score of the regressions? If unreported bugs count,
what about unreported regressions?
