besu-hidden-command-line
command line options for hyperledger besu that are not "generally available"
Experimental offline backup and restore: operator x-backup-state and operator x-restore-state
CLI option --Xnat-kube-pod-name to specify the name of the loadbalancer used by the Kubernetes nat manager
The Tracing API is no longer an Early Access feature and now has full support for trace_replayBlockTransactions, trace_Block and trace_transaction.

Additional Options like --ottoman are P.B. or Pre-Besu and have been removed. Will compile a list of historical command line options maybe if there is interest along with other clients. Geth has much more, even options not technically documented in the code itself as parts of its API do not conform to its specification.
