Hi ZmnSCPxj,

Any benefits of my proposal depend on my presumption that using a standard
transaction for storing data must be inefficient. Presumably a transaction
takes up significantly more on-chain space than the data it carries within
its OP_RETURN. Therefore, not requiring a standard transaction for data
storage should be more efficient. Facilitating data storage within some
specialized, more space-efficient data structure at marginally lower fee
per payload-byte should enable reducing the footprint of storing data
on-chain.

In case storing data through OP_RETURN embedded within a transaction is
optimal in terms of on-chain footprint then my proposal doesn’t seem useful.
