several related applications (etectrum, lnd, etc) require non-pruned node.
If your node is pruned you need to trust on a third-party non-pruned node or service ! do you think this is good for decentralization ?

i think more people running nodes is a good thing. once they are comfortable running a pruned node they can choose to upgrade to a more fancy setup like archival nodes and lightning nodes + block explorers.
of course more nodes are always better, but with terabyte ssd getting cheaper and cheaper, running a pruned node isn’t worth it given the current size of bitcoin’s full blockchain. Don't you think so ?
Another thing is if the blockchain size explodes due to some kind of "vitalikization".
