The risk is represented as being very low to implement this, and would lower gas costs on L1 for less active chains. Given the recent shuttering of PGN, lowering costs for nascent or hyper specialized OP stack chains presents a competitive advantage and is a positive development.
We support this proposal it for its enhancement of cost efficiency across the Optimism network and its ecosystem. The integration of Span Batches, designed to bundle consecutive L2 blocks into a singular batch, is poised to notably decrease L1 costs. This upgrade brings significant benefits to both active and less active chains. Additionally, it plays a vital role in facilitating the development and launch of new L2 solutions, thereby supporting the continuous advancement and strengthening of the OP Stack ecosystem.
