Ok, but this is an Apples vs oranges comparison. (Carlos!)
We are talking about software support here.
The vintage products list is specifically targeting hardware support; e.g. how long Apple will keep spare parts in stock. After a set number of years they purge stock and you are SOL going to Chinese third party vendors and places like iFixit for batteries etc.
Not really; vintage macs turning obsolete are being dropped from the macOS support very reliably. I.e. the 2015 mbp was dropped from 2022 macos release like on the clock.
