Well, at this point, I think 9.6 is going to go out like this, unless
Tom is willing to do something today. Multiple people have expressed
clear support for adding something along the lines you've suggested, I
too am in favor, and I think it's unfortunate that Tom didn't do
something about it before now. But I'm neither willing to commit a
patch to fix the day before rc1 nor to argue that the whole release
cycle should be put back by several weeks on account of this issue.
Once we open the tree for 10, I'm willing to pick this up if nobody
else has gotten to it before then.

I realize that's probably not the answer you were hoping for, and I'm
sorry about that.
