I can't speak for the other guy about his intentions, but I certainly do it with my tractors, cars, and trucks. Isn't that what some people call preventitive maintenance? If I know a fuel transfer pump has over 100K miles on it, with a road vehicle, I change it. I call that cheap insurance for $35. I just changed all the fuel injectors in my Ford F250 turbo-diesel - and it was running fine. They had over 150K miles on them, and I'd rather change them now then deal with it 1000 miles from home. With every one of my diesel trucks (I've got five), I pull the injection pumps off every 200K miles, pull the pumps apart, and reseal, rebuild, or replace them - and every time so far, they were running fine when I tore them down. I can say, I've never one go bad on me, and I've never been "dead on the road." I admit though, I know how to work on pumps. If I had to pay $500-$1000 for a pump, I might wait until it quit. One problem is, if you wait until it quits on the road somewhere, you'll probably have to wait for parts and pay top dollar.
With tractors and power units - I check water-pumps whenever I think of it. If I find one that's getting a loose bearing, I change it or rebuild it before it leaks or flies apart, not after. I had one come apart once years ago (actually a fan-bearing) on a 3-53 Detroit Diesel and the fan went through a $600 radiator.
In regard to checking injectors in the way you describe, yes that will tell you it works, or it does not - and not much more. It's just as easy to check it properly on a nozzle rater, and by doing so, you can predict how long it's going to last into the future. In some circumstances, you might not care - but sometimes it DOES matter.
It's the same mentality when you pull a good running engine apart for one reason or another, but once in there - what do you do? Let's say there's minor wear, but it ran fine - yet you've already spent the time taking it apart. I go through this kind of sh*t all the time. Do you put it together as is and see how long it will go, or renew even mildly worn parts as insurance? It's even more problematic when doing it for a customer - especially one that does not want to spend any money, yet will complain four years later if anything goes wrong.
I see nothing wrong or unusual with either mindset as long as you're willing to accept the consequences of your actions, or lack of action.
