People have left my "repaired" cords alone. Even found one sitting in a parking lot after it fell off my truck.
The longer the cord, the lower the peak.

You apparently haven't seen the reality of this as in a space heater or other higher load device melting the plug & wall outlet receptacle, even tho the space heater would be within the 15 or 20 amp outlet rating.
Now that's just one wall socket plug in. (Another "pass-through" as you would call it) Imagine the potential with 2, 3, or 4 cord's plug-in connections to string them together. There is no guaranteed 'pass through' without any potential high resistance point of issue.
Attached pic is one example.
I prefer 10awg at 100ft though, and 8awg at 200ft, for extension cords. Two 50ft 10awg are far easier to deal with than a 100ft. 16awg copper is fine at 200ft for lighter duty.
This was all about each additional plug/receptacle connection of those choosing to string shorter length cords together. Specifically each connection interface. His exact pertinent words were "The plugs are pass throughs and wouldn't have any effect on amperage". The keywords "wouldn't have any effect" is saying that he believes there won't be any losses at any plug/receptacle interface, period.
The bigger point is... It's not just a dirty, filthy, or worn connection that causes most of the high resistance problems. Most times the contacts are perfectly clean, but in this age of cheaply made plugs/receptacles, the problem is thin contacts in the cord receptacle (oftentimes just making contact onto one side of a plug's blade, or even in cases of 2-sided/sandwiched) the contacts are perfectly clean/new, yet makes too loose and weak point of contact, plus with not nearly enough contact point surface area when they do make contact.
I've seen it numerous times.
A 1 amp load bad connection isn't going to do diddly to a 15 or 20 amp rated plug or receptacle blade. It can dissipate that level of heat. A bad ≥10A-20A load connection not so much.
Also when you start talking 200' distance, something's wrong if you don't have a closer alternate power source to use or a generator to place within 20-50 feet. I really question your experience when you're also talking a 200 foot 8 gauge extension cord. smh
