Soil Digging Suggestions

I know that soil digging currently does nothing and I believe that the devs want to avoid giving extra per tick with the bonus since no other type of work gets bonus per tick since there use to be tree chopping but thats been removed.
Some suggestions for soil digging is to decrease pleghm use(even though its pretty low cost already)
Increase the max soil one can carry at once even further than the 15 kg max.
Increase the drop rates of things that can be dug up, or even, allow players to dig up certain items at intervals of 100 or so soil digging, the higher the digging, the chance to get rare items increases(these rare items should still be rare to get even with the needed soil digging to obtain the items.
