Then there will always be someone else that will do it. Someone will buy them to repurpose them, or reverse engineer them...
“I don’t care what anything was designed to do, I care about what it can do.”

We don't care who repairs the devices... If a vendors price is no longer the lowest, we'll just shift to a vendor that's cheaper. If that vendor happens to be Apple themselves, the so be it. We care more about repair turn around time than the price. FYI, I'm the lead tech in a K-8 public school district in charge of overseeing the management and repair/replacement of 4,000+ iPads, 2,000+ Macbooks, and 500+ Chromebooks.
I'm the lead tech at a K-8 public school district in Illinois and can confirm that none of the districts that I collaborate with care about the iPad's repairability. We all do the same thing... We get our ACiT and ship the things off to be replaced by Apple under Apple Care. I personally replace 10-15 of these every week from our fleet of 3,000+ iPads. At our district specifically, the cost of repair is passed on to the student and their parents. We don't care how easy it is to repair. Only that it can be quickly put back into stock to be made available for a student that needs one.
