Clover trail is long ago documented and Microsoft, unless something has come out I haven't read, has said it will maintain Version 1607 for that class of processor until 2023. This is probably because the issue is because of the chip maker and the PR of dropping the devices that use clover trail.
I am a person who's always ran his computers to well past what most people would consider "their expected expiration date," so I am sympathetic to those who like to do so. At the same time, it is well known that 5 years is the maximum *reasonable* period of time you can consider a computer to be functionally current and completely supported, and not just by Microsoft.
There are a very great many people who elected to upgrade devices to Windows 10 that the manufacturers of said devices never certified as being compatible from the outset. That, in and of itself, makes that decision an "at your own risk" situation. These machines, on the whole, were near or past the end of their service lives when updated.
I simply do not believe that it is reasonable to believe that commercial entity like Microsoft is responsible to maintain backward compatibility "in perpetuity" for hardware that is long past its practical expiration date. Even many flavors of Linux, which is much better about compatibility over very long periods of time, don't do this.
Software makers are always going to focus on hardware that is current, as in on sale now, or was on sale up to perhaps 5 years in the past. Computers that are older than that can, at any moment, go out of support for newer versions of whatever OS they're running, not just Windows. It is, though, a PITA if Windows 10 keeps trying to do its next version updates. I suspect that a feature that will be coming down the pike is detection of whether the hardware in question is "on the list" as supported for a given version update and it being skipped, and a message to that effect communicated to the owner, and also telling the owner what the "drop dead" date is as far as security updates for the version of Windows 10 on their own machine.

. . . the presumption of innocence, while essential in the legal realm, does not mean the elimination of common sense outside it. The willing suspension of disbelief has its limits, or should.
