That seems to me an unusual application not deserving of a primitive.
And }:: is being held open for 'emend', modification inside a boxed
structure.
You are right to point to rank as the basic problem. Maybe a way to
give rank to u} would be a more general solution.

Would this be worth adding as a primitive?
I had some use for it, but not all too frequently.
} can be viewed as a three noun argument function,
but you can only change its rank wrt two of them.
That’s why I’d like to have this complementary one, too.
