You're preaching to the choir here, I've been in the trucking industry for 23 years and counting, and at one point, even retrofitted my old diesel pickup with water injection.
That all having been said, water injection is not a thing in mainstream use in run of the mill diesels. It's actually virtually unheard of outside competition. It's actually been in more production cars with gasoline engines then ever used in diesels, for that matter.
What you forgot to say about diesel engines is that despite all their benefits, their initial purchase prices are many times higher. In the commercial industry where trucks are routinely run into the 1 to 1.5+ million kilometer range the benefits obviously outweigh the negatives, but for the typical grocery getting pickup truck market, if you do the math, the diesel will typically cost you *more* over the lifespan of ownership, taking initial purchase price and increased maintenance costs into consideration. Even for the "occasional hauler" market (IE, the <10,000KM/year RV tower) the advantages of a diesel are still not really there vs the cheaper purchase and operating cost of a gasser.
