As done in https://code.wildfiregames.com/rP20631, we should update all gatherer actors so that they can support having idle carrying animations.
This should/could be done incrementally, but in general I think a class of unit should be done across all civs at once.
They would probably just rely on Periokoi or some foreigners. I would personally say that the latter is a much more likely case since cavalry were generally the wealthier stratum of society. I would personally say that Olynthian Allied Cavalry would be plausible since they were employed during the Corinthian Wars.
Another relevant thing to consider adding is walking empty animations. In that sense, when units are assigned an economic role, they walk using the implements they are using for the task even if they have no resources.

@Alexandermb Maybe you want to do the missing seeding animation?
As far as I can see, here are some WIP files, but I guess @stanislas69 could know more about this:
