We should go by our guts instead.
I prefer to follow my owners manual, and not overthink it. I refuse to play Russian roulette with my cars. I plan on keeping them for 15-20 years. But all you Extended oil change worshipers can do whatever you want. My 9 year old civic, that I bought new, does not use any oil between changes. Inside the oil fill hole is spotless. FWIW, I just bought a 2013 civic and plan to change oil based on the oil minder system. No UOA's needed!!!
