"More crazy things than table layout". Good one. ;)

Oh. I was hoping that everyone would agree with me that the original B

It's mildly magical ("this item is immune to space-between and
space-around"), but sure it could work. Much better than A and B.

To clarify: is C about wrapping the abspos into an anonymous flex item?
I certainly hope so, but "placeholder" somehow sounds more scary than
something as simple as that.
