LGTM! One small comment.

Can you talk to @lehins about this? If the intention is to move this to ledger, we should put this in Cardano.Api.ReexposeLedger.

Yes, we can definitely add this to the cardano-ledger-api. Feel free to submit a PR that adds them to this module an exports these lenses together with ValidityInterval:
