RCA, the TMA was hard wired and they made it easier to transport the chassis for service. Even the earlier B/W sets that had a separately tuner assembly had holes in the in the chassis for hanging the tuner.
The PITA was lining up the indicator wheel that was driven with the tooth belt.

Honestly, even given that fact that the tuner can be mounted on the chassis, it may save you about 1 minute of labor, however it seems the real benefit is to the tuner itself, avoiding stressing all of the wires going to it.
