Well, besides the summoning spells, full round spells were put in place to allow someone the chance to disrupt a powerful spell. With the summoning spells, they generally seem to be too weak to make it worth the effort to cast them. Maybe they should be turned into a 1 action spell, but don't have the creature appear until just before the next round (which is pretty much how I've been playing it as a house rule).
