In op_observer_impl.cpp, logApplyOps is called from 4 different contexts onUnpreparedTransactionCommit, onBatchedWriteCommit, onTransactionPrepare and onTransactionPrepare with different combinations of parameters.

In SERVER-124140, we added another parameter computed only when it is the last op in a prepared transaction chain.

We should separate the core logic of logApplyOps to reduce the parameter complexity and improve readability.
