Lots of rose colored glasses being worn here.

I will take modern rust prevention tech every day all day. The control modules and circuit boards are a hole in repairablity, and there’ll be a wall where nobody makes them anymore and the specs are not published (considered proprietary/trade secret/whatever), and that whole vehicle will just have to be scrapped. The world won’t ever see the end of old body-on-frame vehicles with crate engines. Speaking for myself the “rose colored glasses” is a wish for the best of both worlds. I wouldn’t doubt it’s out there being done somewhere, but I’m sure it’s cost prohibitive to do it, or people are doing it for themselves.

Maybe I’m just complaining because I don’t personally have the time/knowledge/workspace to do what I want in that area. C’est la vie.

They used to be. Go back far enough in time and you could climb up under the hood into the engine bay to work on it. All that went by the wayside to get smaller packaging, lighter weight, and better fuel efficiency.

Now you need special tools or special code readers to solve/diagnose all vehicle problems. The large scale farmers are dealing with this now with the large combines and harvesters needing a tech with special equipment to read all the codes where the older tractors from the 70s and 80s can be repaired.
