That, and several other things. If you can figure out how to propagate a block without re-propagating all the transactions everyone already has, you address the large-blocks-slower-to-relay problem, and additionally create an incentive for miners to mine blocks consisting of publicly broadcast transactions (versus a bunch of secret ones mined with secret agreements). Democratizing transaction selection takes a bit of power away from the miners and gives it back to the network at large. GBT is another piece of that puzzle.
