I suspect they'd stop at automatic rendezvous & docking. Use some sort of cradle system that holds heat fins, power, etc that boxes of racks would slot into. Once they fail just pop em out and let em burn up. Someone else will figure out the landing bit

I won't say it's a good idea, but it's a fun way to get rid of e-waste (I envision this as a sort of old persons home for parted out supercomptuers)
