It would be nice to see it come back once server latency is fixed and they corrected the problems third party tools had to fix in XI.

-Give each job a set number of mannequins designed for the player to set up for gear swaps.
-Let macros be able to execute gear swapping from the mannequin so macro line increases aren't necessary. This allows SE to not have to worry about botting by someone making an infinitely looping macro.

Until macro latency is fixed it's a worthless endeavor to pursue, but once it is it wouldn't be bad.
