Not a good reason. First, Ford starter switches are pretty robust and just don't fail that often. Certainly not often enough to explain all the jury-rigged starter switches. I think the starter switch on my 58 year-old Ford 4000 is the original. Second, even if it the starter switch does fail, it is actually much easier to replace the switch than to jury-rig a different switch. (In case you're not aware, the neutral interlock on a Ford is mechanical; there is no neutral switch separate from the starter switch.) Either way, you'll have to make a trip to town to buy a switch. Of course, I understand not every town has a Ford dealer, which brings me to my third point: In an emergency, it's a simple matter to disconnect the starter switch lead and touch it directly to any ground. Instant starter switch! There's no need to butcher your dashboard to install a redundant and unnecessary starter switch.
Let's get serious: There's only ONE reason a person would bypass the neutral interlock on a Ford: It's because that person believes safety devices are bad things. There is a word for people who believe such things...
You make a good statement pertaining to your 64 model tractor with it's push button starter switch on the transmission, but in 1965 Ford went to a 2 wire safety switch that wires in series with the key switch, the switch was on the outside of the transmission shift top easy to get to.
In late 1966 they moved the safety switch inside the transmission, requiring the shift top to be removed to get to the switch, taking the shift top off to replace a safety switch and then reinstalling the top while keeping the shift levers in place out in the field is not a simple 10 minute job.
Ford did make the wiring with male/female plugs on the outside were the switch could be bypassed temporally to get you going
New replacement switches are not as reliable as they once were, I've had 3 fail on my 69 model 4000 and the switch is bypassed at this time. If the switch fails on my 75 model 6600 row crop the deck has to be removed to access the shift top, that's a good days work to replace the switch and get the decking back on.
I agree they should be replaced and not be left bypassed but there are valid reasons for bypassing them at times when you have crops that need to get done.
Item 71 is the switch

Today's Featured Article - An Old-Time Tractor Demonstration - by Kim Pratt. Sam was born in rural Kansas in 1926. His dad was a hard-working farmer and the children worked hard everyday to help ends meet. In the rural area he grew up in, the highlight of the week was Saturday when many people took a break from their work to go to town. It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer. It was an Allis-Chalmers tractor dealership,
