Some people sit at red lights with the clutch pulled in, I am not one.

I would expect that technique to lead to premature clutch spring failure ... but maybe not? Just can't imagine it's a good idea to have the springs compressed and bound for ages at a time without some loss of spring tension?

My wife is compressed and bound for ages.
No damage done.

That's because you're putting in contact a part that turns, with a part that's immobile. Not to be done for too long.

Some of your valve springs are compressed whenever the motor isn’t running. Does that lead to premature failure?

I agree there, and the clutch springs are already compressed all of the time anyway

Until you reach coil bind, that is the basic issue with a spring in compression, valve train springs do not operate in coil bind mode, my perspective on the clutch plate binding, well known issue.

Simarly i downloaded the specification criteria and application engineering for "rubber" O rings, was very enlightening, compression set failure of O rings can be based on incorrect O ring and or incorrect recess dimensions for appplied installation environment. HTH j.
