OK K.O.! Let's Be Heroes - crossover overload

Wasn't one of those crossovers an omega-crossover with every show the network cancelled and could be read as scathing criticism of said network?

Reminds me of how Payday 2 makes it so that John Wick, Jacket from Hotline Miami, Ethan and Hila from H3H3, Jimmy from Hardcore Henry, Bodhi from Point Break and (possible impersonator) Tony Montana from Scarface all share the same universe.
