When querying storage for historical blocks, we need to decorate a whole apitAt object with await api.at(blockHash). However, if we only need to one-shot query for storage for a certain block, there will be a lot of wasted resources decorating api.*.
As a result, if we need to query storage for a lot of blocks (not simultaneously, but at high frequency), this will cause significant performance issue.
Can we have a more efficient way to query one-shot storage, such as await api.queryAt(blockHash).section.method()? In this way, we know it's only querying storage so can skip other unnecessary decoration.
For multiple queries among api.* for the same block, we can still use apiAt(blockHash)
