I was 7 when I got an Apple ][, bit older by the time the //e came out, no clue what my parents paid for, but I'm pretty sure adding soldered in shift-key mod for ][, and NMI switch -- and burning new ROM for enhanced character set they introduced post //c -- for //e voided whatever warranty existed, but I never needed them.
When you're paying $20K for hardware, why would you possibly not add $200-$300 for AppleCare to extend warranty from 1yr to 3yrs?
FWIW I've purchased MANY Shiny Things from Apple over the decades, and always get AppleCare. I have only ever needed it for laptops, iPads, iPhones, ya know, stuff that gets dropped because gravity, or goes through the washing machine because whoops, I'm multi-tasking, super-busy and forgot. Since iPhone X, washing machine doesn't kill iPhones, 'cuz I've tested that twice so far without intending to; nothing dramatic happens.
Mac Pro... if it shows up and works, and keeps working for a week or two, then I fully expect it to stay working for another decade.
Out of dozens of Apple purchases, I think 100% of computers were still working when I passed them on, or retired them. Laptops and iCrap, not so much. On the flipside the iCrap sure does make my stock go up and pays for my Mac Pro, and house, and cars, ad nauseam. Go iCrap, it's ShInY, reVolution4ry, and magical!
Dear Apple: I used Mac Pro as boat anchor and now it Won't Go. The system I'm bringing in resembles the computer you sold me, not at all. Just overlook all changes and please fix. Tnx!
