Yeah its also what i thought, it can keep up to date with newer blocks checking the pow and updating the balance of your wallet safely, or send transactions from your wallet's address safely, add newly generated "virgin" address but thats it they have to trust the pow for any utxo that transfer fund from older blocks, cant really mine , cant import safely new address that already contain a balance from potentially older blocks ( or they have to re download everything).

I dont know what is the network demand for blocks probably newer blocks are in higher demand than olders but pruned node cant fully validate all tx and have to trust the pow for any transactions containing inputs from older blocks.

pruned nodes dont have Pow, pruned has nothing to do with PoW
the hash is not about PoW its about the 'chain' of Id's where the chain is a unique cryptography hash that is formed by the unique data of the block which contains the ID of the last block.
destroy the block means the ID wont be able to check the block is still in correct form, because there is no block. meaning

though pruned nodes do validate all transactions when it does the IBD. it then does not keep the blocks. meaning it has to trust that a hacker hasnt manipulated the data afterwards because they cant just do a local re-check in seconds to ensure the database they have has not altered.

pruned nodes are not supposed to be deemed as full nodes minus archiving
but instead litewallets + better verification at first sight

in short,
not fullnode minus
but litewallet plus

other features disabled when 'prune' is set. is
when not storing all UTXO's and only storing UTXO associated with your keys. you then dont relay other peoples transactions. because you cant verify transactions at the relay stage(unconfirmed)

They can still check the pow from block headers to make sure the transactions that they cant validate in New blocks are considered valid by the majority hash rate.
