With the Framework though, the CPU (motherboard) is intended to be replaceable. There will likely be (assuming there isn't one already) a secondary market of individual parts.
Alder Lake and Zen 3 have been out for a while now, so I do not think it is unreasonable to expect a brand new laptop to ship with either of them.
For a Dell, HP, or other multinational conglomerate who gets new chipsets in advance from Intel and always has a dozen or more models on the never ending merry-go-round of 'hype the new, dump last seasons at Costco on the people who don't know any better', no, it's not unreasonable.
For a small batch manufacturer who's been shipping laptops less then a year and is still effectively on their first model release? All in the middle of a pandemic induced supply chain fiasco?
It kind of is.
5000 series Zen 3 has on desktop. Zen 3 based 6000 series laptops with RDNA2 graphics are still newish and a little difficult to get. Even from tier-1 brands.
AMD was also a little late to getting Linux support into these computers. 5.17 (released a few weeks ago and is what Fedora 36 will release with) just got support into the Ethernet driver.

Mobile Alder Lake just launched (in Feb?). Don't confuse the desktop with the mobile variants-especially when you are considering driver support.
That being said, I'm also waiting for an AMD CPU. Given that it is the most requested feature, though, I assume they'll be there in the next iteration.
The whole "it's more green" thing is marketing fluff.
Recycling is the worst of the three by far.
