As others said, a minor upgrade does not obsolete v1.
The main obsoletion factor (except for the bleeding-edge cool-kids) is software. This is why mainlining and upstreaming (kernel, Gnome) are key factors to deliver on their promise to fight planned obsolescence.
Being able to upgrade the PCB(CPU/RAM/eMMC) sounds doable, but they will likely not commit to it just yet.
In general, @amosbatto pointed out to me that they plan to sell parts, at least batteries. (possibly more, e.g. displays, modems, cases)
So I added that to the Promise Delivery Chart.
From what we saw so far, the phone will most likely have one of the highest repairability indexes ever, on par with the FairPhone.
