My memories are of tanker and chicks departing on a trans conus flights on ALTRV flight plans. From one coast to another crossing God only knows how many differing sectors of many different centers all in block altitude fashion. Your the expert, if one of those guys wanted us at a hard altitude thruough his small piece of sky I guess we would be obligated. I can tell you it would be a pain in the rump for the guy in the right seat of the tanker along with the guys being dragged. I don't imagine the guy in the preceeding sector would be all that happy either as what is already a gaggle is made worse as the flight reconfigures to meet the suceeding sectors demands. I was under the impression that once an ALTRV departs from A to B needing a block to contain its operations it was allowed to remain in block fashion till no longer needed.
