With it being modular there's always the potential for CPU upgrades in the future. But yes, it's much less performant than a modern x86 or Apple Silicon device. Performance isn't the primary goal, though admittedly it would be nice.
This will of course never happen but imagine if there were an M1 CPU module for it.
Qualcomm is maybe more realistic but from what I've heard it seems like they won't even talk to you if you're not ordering in huge quantities.
