One of the aspects which I do usually feel rather scummy for is the use of tesseracts/enderchests. What I really should make, at some point, is a frame-moving quarry/miner ship (not entirely sure what I'd prefer to use for it), which automatically lays down a bridge and tracks, to drop off at a base via carts. This will likely wait until I have most of my infrastructure, as it'd be good for maintenance stuff, but the ever-increasing delays would probably struggle with expanding bases.
Rather hard to do, but I do like enderchests/tessaracts! Maybe use a turtle to transport the items with a Turtle Teleporter?
