Do you think that we have used this rule in past?
Anyway I understand what you mean but it is questionable if make sense
to predict all changes which can happen. I would consider if anybody
remove this dependency without fixing test suite as bug which should be
fixed. Also tests should detect this and report issues to stop this
before patch like this is applied.
