Actually, this entire blog post came out of a short chat at Git Merge a few weeks ago with Jeff King. I argued more or less this and he didn't _entirely_ disagree, though he has good counterarguments on the list over the last few years, so I don't really know how he thinks about it ultimately.
I would write this to the mailing list, but I thought a conversation that includes people outside that list is more interesting to me. Ultimately I'm not sure if I'm dumb about this or the whistle blower that's willing to actually say "maybe this isn't the right call"
