I'm sorry I read this a lot and this is kind of an insane thing to say? Classified OLC memos giving legal cover to any military action has been a fixture for the last over twenty years! Congress never abdicated power, it just, by the nature of the constitution, practically has SO much less power than the president! The president is a single person that people elect, they expect the person to be a leader, and congress will always, always play a following role so long as the president has unilateral power over the military, is directly elected, and just in general has expansive interpreting authority over laws.

You know who doesn't have as much power? The swiss head of state, so weak you can't even reliably name them! THATS what it looks like to defeat personalization, not some hand wringing hoping a system does something that it wasn't designed to do.
