Yeah, it doesn't make sense for errors/warnings: Those should be "right next"
to the thing that caused them (so I prefer the +/- Numeral for those).
However, with Notes, it makes a TON of sense, and IMO, should nearly ALWAYS be
used.
Without them, we end up getting 'errors' and their notes are completely
unintelligible, because they are spread out around the file and in no
reasonable order. It makes it so figuring out "this is an error only because
of these instantiations" is impossible.
