IMO, if you are using and steel STEEL with the appropriate hardware properly installed, there is virtually no risk of a clutch explosion. If you are tracking the car or taking it to the strip with 7,000 RPM potential, the equation changes.

Our Mule Vehicle: 4.6L 4 Valve 6 speed manual trans routinely was shifted at 8000 on the street, and a lot of the high rpm shifts were caused by the people not being prepared for the rapid rpm increase of the engine.
Others did not have a clue how to shift, and missed gears, rode the clutch, etc.
We were replacing the steel flywheel and clutch system around every 6 months do to heat stress cracks in the STEEL flywheel.
If you are changing the flywheel you might as well change the clutch parts at the same time.
The car did not have a scatter-shield on the car.
Common sense said rather than pay for very high medical bills (someone hurt) due to a issue, we changed the parts.
So I provided an example that differed from your opinion. Nothing wrong with your opinion.
A Steel Flywheel and good clutch system installed in a PONTIAC vehicle could still have issues over time, depending on the driver and the abuse the parts saw. Blanket Statements rarely fit all conditions.
