Pull-up is not necessary at the finish cylinder, so why do it?

OK, I've lurked long enough. I'll probably be sorry, but....
Why not? Aren't we trying to puncture the edge of the cylinder very near its
bottom at maximum speed? Now, an instant later, we find ourselves 499' AGL
at redline less than a mile from the airport. Seems to me we sort of have to
pull up even a teensie bit to get slowed down and sorted out and into the
pattern.

Some math in prior posts points out that the length of the arc of the
cylinder we are trying to reach (on an AST at least) is even shorter than
the 1km long finish line. For me at least, all the cylinder does in this
case is move the bottom of the high speed pass up 450'. Maybe that's better
or safer, I'm not sure; it's certainly not obvious to me.

Additionally, the rules state that the 4 mile radio call for a finish is 4
miles from the finish point, the cylinder center. So with a 2mi radius
finish cylinder, radio calls come about a minute before the finish. With a
finish line, the 4 mile radio call gives 2 minutes of warning. I'd kinda
like as much warning as possible about who's nearby.
