Please describe the feature you’d like to see added.
maxfeerate is a sanity check optional parameter used by clients to ensure transactions submitted to the mempool and relayed to the network by a node withsendrawtransaction, testmempoolaccept and now possibly submitpackage #28950 does not exceed the maxfeerate value.
Node will reject transactions whose fee rate is higher than maxfeerate.
maxburnamount is also a sanity check optional parameter used by sendrawtransaction now possibly submitpackage #28950 to reject all transactions with OP_RETURN outputs greater than the maxburnamount.
Should we enable passing maxburnamount and maxfeerate  as startup-config options to be used by those RPC calls instead?
Is your feature related to a problem, if so please describe it.
