Here I go into another way-too-long post trying to get my thoughts established, but it bugs me and therefore I think it’s a worthwhile endeavour.
The trigger for this is Tom Babin’s article here. Go take a little time to read it, it’s very worthwhile to go through. Even if you’ve read it, it’s worth scanning through again because I will doubtlessly refer to it.
That is far from the only source I’m going to draw from, however.
