We must

Yes, yes, you learned some words from that math
paper even if you only dimly perceive what they
mean.

Now, let's suppose that paper was never written.

What is this "collapse"? What's going to happen
to SR if it turns out that you have a vector operator
that doesn't form a group on the vector space of
velocities?

Elementary, my dear Randy. It happens that in SR you
initially take a Minkowski spacetime which does not rotates,
and the result, once you've added two velocities by means
of Einstein addition, is a Minkowski spacetime that has rotated
exactly by an amount that Thomas precession can described.
How can that be?.
