For the Hegotá agenda: EIP-8198 (Quick Slots) now has an upstream-facing executable EL implementation of the schedule-driven direction.
4bef25e89530a6ea2fc46709db910d5b655b241bef914fe55dd252b60a718fec013ae2a6ee15054eThe implementation preserves the current Hegotá-facing behavior while using synthetic later duration eras only to prove that the same production paths compose without new duration-specific EL branches.
One specification distinction remains narrow and explicit: one-time capacity transitions use
new / old, while persistent base-fee wall-clock responsiveness usesactive / pre-schedule-baseon every block. The EL proof exercises repeated eras so those two semantics cannot collapse after the first transition.The question I would like resolved during EIP-8198 discussion is: should the EL side pay the refactor cost once so later slot-duration reductions become schedule/config changes rather than new transition-specific execution logic?
