"Does the hardware physically work" isn't ever really the question under consideration, though, for better or worse. For Macs specifically, it is going to get increasingly difficult to even test things in the coming years. Mac x86 builds are by far the flakiest on GitHub in my experience, there's no expanding capacity, only refurbished machines 6 years out, and the number of users is dwindling, not to mention the enormous performance gap. So what do you do? When we last asked about it in a project I work on a few users expressed interest, so we kept it, but that isn't forever. The JDK as a project probably has a different risk profile than most other projects too so the cost of keeping around that code can be relatively high.
Not saying it is always good, in fact I would say there is rarely a "good" happy outcome in these cases, just trying to give the alternative perspective when you have to make these calls.
