This is what GNU ld uses. I agree with you it's a poorly chosen sequence of words, so we need to decide if we want to stick with what they currently output or introduce our own notion of statistics. At this point I can also say that we can output something more meaningful/fine-grained.
Considering this isn't a very common option for ld(1) we can probably go for the path of breaking compatibility but I would like to have a more detailed discussion about it before taking any actions.
