neutral in swtch box

I think the analogy I gave at the beginning is pretty accurate: should the customer have to pay for #12 to every device just in case someone wants to come in later and install a 20A breaker?

Or #10, I frequently see panels with sp30 breakers on 12 & 14, usually a result of changeout fusebox where installer was matching original glass fuses.
