Not quite completely correct. IFR traffic receives separation from other IFR traffic and participating VFR traffic. It's the VFR traffic that gets separation services based on workload.
As for the re-routing and such around ORD, that's the unfortunate consequence of flying general aviation. It's just not that easy to route aircraft that are slower at full speed than larger aircraft fly on approach, when you have to make allowances for wake turbulence, and then mix in that many private pilots are just slow on the radio often requiring time consuming repeats and explanations. Not saying that all of them are that way, but based on experience in/around San Diego, LA, Seattle, Vegas, Dulles, DC, etc., it's just too hard.
And lastly, about things working fine for 75 years, what's happened in the past has no bearing on what will happen from this point forward. Before you get too deep in nothing needs to change - interesting that the video you lamented doesn't mention any flight above 400' AGL.
I'll predict that the rule will limit model flight to 400' AGL - it won't be an advisory circular anymore, but rather part of the FAR proper.
