In the context of a plane, still potentially dangerous, but no more so than the idiot shoe or undies bombers. If they tried to assemble it airside in the sterile area then no real threat at all.
Their plan was for suicide bombers to assemble the devices in flight so it wouldn't have mattered if they'd blown themselves up "prematurely" because they were already in the air. Even if most had a "squib" explosion there were according to the investigation multiple flights targeted and all it takes is one.
Their plot was closer to "viable" than it was theoretical. While not a fan of the liquid restrictions I have zero sympathy for those who would put lives at risk so they can enjoy their favorite seltzer. Boo-hoo.
