 The Custom Gas Token beta feature has been deprecated. Beta features give developers access to early versions of highly requested features, allowing us to validate demand through usage data and user feedback. Since May 2024, usage of the custom gas token beta feature has steadily declined as ERC-4337 and robust paymaster services gained traction. 
 
-Based on this trend, the beta feature was deprecated instead of being moved to the OP Stack standard configuration. While the custom gas token code has been removed from the Optimism monorepo, chains can choose to maintain their own forks at their own risk. 
+Based on this trend, the beta feature was deprecated instead of being moved to the OP Stack standard configuration. While the custom gas token code has been removed from the Optimism monorepo, chains can choose to maintain their own OP Stack Fork at their own risk. Future upgrades to the OP Stack will not be compatible with custom gas tokens. Recommendations for existing chains that use custom gas tokens and new chains are discussed below.
 
 Additionally, advancements in Account Abstraction (AA) tooling now enable gas payments in any token, offering better alternatives for the limited number of chains that require this feature.
