Do people think Aizen knew all about the Quincies?

I think it is kinda interesting that Juhabach went after Aizen's left over Arrancars and tried to convert them to his army or kill them. Maybe he saw them as a threat? I think Juhabach was not at the level of Aizen when he evolved to his last state and hid out. Or maybe that bs excuse applies that he could not contain all his powers in the little medallion. Even 17 months later since that incident and stopping the Fullbrings, the Quincies made them look very weak.
