Just like the non-prompting polls, I think AA polls are interesting to have once in a while, just to see the contrast. They give you an idea of how things are going in general and the contrast shows the gap between the population as a whole and the RV or LV population.
But just like the non-prompting polls, the media should be clear when reporting the results and the poll averaging sites should not lump this without adjustment.
They also show the potential of a candidate. Hillary just needs to find some of these voters and register them. Still, I wish media outlets would explain the difference between this poll and RV/LV polls.
