I don't think they believed that AGW was due to water vapor because it is likely they don't believe in AGW in the first place. The greenhouse gas effect is a choke. It slows the transfer of energy. It doesn't heat the surface of the planet. It heats the atmosphere.A number of people here have argued that AGW was actually due to water vapor. And the net effect of clouds on temperature is still not settled science to my knowledge.
And yes, the role of water vapor works as a positive (GHG) and a negative (clouds and precipitation). And yes, it is not only not settled it is not well understood and a very long way away from being settled if ever. There's no data record. It's water vapor and clouds. It might as well be a ghost.
