That, and there was a lot of "Jailhouse lawyering" going on where we would try to circumvent the intent of the regs for a happier outcome. The abuse of the ampacity tables once THHN showed up on the scene (magically everything was a 90C circuit) was epic.
(I will say this, no one was happier to see the demise of TW and THW than me.)
And back then you never found an electrician who derated their ampacities based upon the number of wires in a conduit. Nor did you find a "AHJ" (inspector) who gave a hoot. And strangely enough, those buildings are still standing. Hmmm...
So a big part of the evolution of the NEC (what we use here in North America) is due to us sparkys trying to get around what the Mike Holts of the world were trying to saddle us with. :)
