Constant GC_REMOVE_FINALIZED_ROLLUPS 

pub const GC_REMOVE_FINALIZED_ROLLUPS: Config<bool>;

Kill switch for GC removing a finalized shard’s old rollups. When off, they stay in state and in blob, and new rollups don’t record finalized.

NOTE: Off by default until no binary that predates HollowRollup::finalized can read state written with it set. See the note atop state.proto.
