There will be some confusion on this subject because terminal strips were a rules violation in past years. There is no longer a rule against terminal blocks except as below. See Sec 3.2 Wiring the Robot Controls of the robot docs for explanation.
"Except as noted herein, each Ground (GND) wire from a speed controller, relay, or Robot
Controller must go directly from that item to one of the 12 Common (-) terminal tabs on the
circuit breaker/ fuse blocks.
Exception: The Ground (GND) wires from low current items such as solenoid control and
rotating light relays, custom circuit, optical sensors, LEDs, and fans may be connected as a
group to one common wire leading back to a Common (-) terminal tab."
I would have to ask why? The terminal blocks add one more spot for failure due to loose hardware, one more spot for high resistance connection, and one or more additional crimps that could be made wrong or will fail with vibration and it adds precious weight.
