In my shop, we always put at least 1 Qt of ATF in the torque converter for lube, during initial startup and lube the pump bushing with assembly lube.
Yes the converter will fill fairly quick but that first few seconds or more, before fluid is picked up and circulated through the trans can be hard on internal components that are dry.
Would you start an engine with no oil in it then add oil right away or run a differential dry and then add oil right away, I would hope not.
