I'm confused. My understanding is that they didn't drop support for all Intel Macs in Sequoia. My 2018 MBP for example is still supported. The last Intel Mac Pro in your example is also still supported.
My MBP hasn't hasn't been _fully_ supported for many years. The M1-specific features started rolling out in 2021 - ability to run iPad apps being the most obvious one, the ability to get the globe view in maps being the most questionable. IIRC, my MBP did not yet have a M1 Pro/Max version available for sale when they announced the M1-specific features.
The point being, having AI features unavailable doesn't make the Mac unusable any more than it makes an iPhone 15 unusable. Those parts should continue to operate the way they do today (e.g. with today's Siri).
