In merge request !172 which updates substrate to v0.9.42, we have to choose the value of MaxSetIdSessionEntries, the maximum number of session to remember for equivocation handling. Equivocation offenses are detected by an offchain worker and submitted as an unsigned extrinsic. What value do we want for this? Equivocation handling will certainly be a simple blacklist (no slashing) with manual unblacklisting through onchain governance, so the polkadot example BondingDuration * SessionsPerEra does not apply to us.
