Inbox was kind of an experiment and competition with their main GMail offering. It had resources that ABC probably felt could be used elsewhere, so they took what were probably the most used features from it, merged it back into GMail and killed it. Docs doesn't have anything in their current product line that they can do the same to, they might merge another product INTO Docs and kill that product, but never Docs itself.
