Immediately after CoIE,things were not all that messy. There were pretty large question marks hanging over Power Girl, Wonder Girl, Fury, and the time that had passed between Byrne's Man of Steel mini and his Superman relaunch. Still (in my recollection), it didn't start to get head-scratchy until DC retrofitted Troia, and launched Hawkworld as an ongoing monthly. And it got progressively worse as it went forward, with continual attempts at historical patch-plumbing and writers insisting on restoring their childhood sacred cows.
At the same time, Pre-CoIE Superman's environment was thick! He was The Last Son of Krypton (except for is cousin, a bottled city full of miniaturized refugees, and a veritable army of criminals in a ghost prison). He had a full-time gig as a reporter, and then TV anchor, but still spent oodles of time out in space while a legion of robots substituted for him. He had this constant romantic quadrangle going between Clark, Kal-el, Lois, and Lana (plus Lori and others). To keep things challenging for him, kryptonite had become more abundant than sand. He could travel through time, but didn't learn about the great crises of the future and try to avert them.
Superman's surroundings were also sometimes a little silly (at least to the emerging aesthetic of the day). He had a super-dog, super-horse, super-cat, super-monkey. One of his most dangerous adversaries was - literally - a cosmic western desperado riding a space pegasus.
Wonder Woman was not much better off. She'd been through at least two Trevor deaths and resurrections by Crisis, and a giant, racist-caricature, mustachioed egg was on her roll of major villains.
All that said, looking back, the continuity might have been heavy, but it wasn't unmanageable. As SiegePerilous02 points out, Crisis seems to have had less to do with cleaning up the backstory than with trying to salvage really valuable IPs that were sinking, and it did that. If cleaning up had really been the goal, they would have followed Plan A, and done a cold reboot, ala Nu52.
Further, Batman had been in dire need of rehabilitation in 1968, and they did it without burning Wayne Manor to the ground. They reset him in one issue, without explicitly writing out anything, and just wrote in him a way that worked better for the times. You don't want Wonder Woman looking through time with her magic sphere, don't write about it. You don't want Superman fighting a fetishy-Zardoz knockoff, forbid using the character. Incentivize writers that want to write the kind of pitch you think will work.
Still, I can see why DC thought it had to do some dramatic, and they did deliver on that.
