This is a problem, isn't it? I mean, what happens when you accidentally
commit something that causes a non-obvious problem?

For example, in the course of bisecting something today, I came across
r112851, http://lists.gnu.org/archive/html/emacs-diffs/2013-06/msg00043.html,
which seems to include an unrelated change to subr.el that has no
ChangeLog entry AFAICS.
