I am guessing the reason you did not take it out was because it would set some nag CEL lights.
The shaft that is felt behind is not that large and should not cause that much restriction to the air flow.
Now if your were trying to get every ounce of power out then that would be a reason to remove it.
My little 1988 Ranger with the 2.9L got a nice coat of the Ford grey when I rebuilt it. Nothing like
taping and spraying paint. When you remove the tape you have all the nice clean surfaces for the
gaskets to go onto. The colors for that engine were gray, aluminum, black and exhaust manifold rusty.
I am not sure if the paint helped or not but it sure got it power back after all of that.
It just frees up clutter and gets rid of uselessness. Not necessary I guess.
I'll erase this in a bit so I don't clutter your thread but I'm a little partial to the grey.
This is my 6.9 I did 10 years ago or more.
I like it. And please don't delete your post. Its all part of the engine theme.

You're probably right about the CEL, but that was so long ago I can't remember.
05+ they are a little moody depending on the pcm flash. My 05 unplugging EGR valve or welding up the cooler never through a code.
As far as I know removing the throttle body on the early trucks will not throw a light. Maybe an 04 down guy that did it can chime in. Or search it.
I just think its cleaner without it.
The '03 reman came to me throttle body gutted. The electrical connectors connect, but there is nothing in there, so sensor, no boards, nothing. I could just cut off the wires.
Done. Fully bolted to the transmission, motor mounts bolted to the frame.
While stuffing each torque converter nut into the transmission at the end of a 36" extension, this cheap nut holder helped immensely. I cut an inch off a finger of a nitrile glove and slid it over the end of the 14mm socket. None of the 6 nuts fell out of the socket
Reaching into the transmission with a torque converter nut stuck in the end of the socket and 36" extension.
