I'm not hoping to get into another fight with EDSBS in the post below. For a lot of reasons disagreements are often more controversial than they should be.
I recognize their argument and much of it has its merits---but like I said I think that overall it's a crutch.
In diplomatic fashion they have presented a middle path, a solution to make the scheduling thing less controversial. I haven't ignored that, and think it's interesting and relevant. But in expending my energies on my disagreement, it often goes unstated that I don't have any personal issue with them and completely respect what they've written and agree with some of it.
In other words I hope no blood is spilled. They're intelligent and can easily navigate the various levels of the argument, that's not in dispute.
