I am glad that SPV wallets are discussed outside the scope of mobile devices! Yes, SPV is a sufficient API to a trusted node to build sophisticated features not offered by the core. SPV clients of the border router will build their own archive and indices based on their interest of the chain therefore the border router core does not need to store (and process) anything not needed for consensus, its memory or disk footprint would be as low as an optimal storage of UTXO.
