However, even if you use or introduce CBlockHeader::GetPoWHash() caching may still be desirable as the PoW hash is commonly requested 4 times per block fetched during a node's initial blockchain sync (once during prefetch of block headers, and 3 times more during validation of a fully fetched block).
