WARNING: Due to experimental protocol upgrades, --experimental-splicing is incompatible with previous CLN versions! You will not be able to reestablish channels with older nodes at all, if this is enabled! If you have CLN peers with the experimental splicing feature, consider disabling this option until they upgrade to support the latest draft spec.
