This class does more than cirq.merge_k_qubit_unitaries. It calls off to cirq.drop_negligible_operations and cirq.drop_empty_moments as well. Will existing tests for this optimizer pass if only cirq.merge_k_qubit_unitaries is called?

Can you point me to where MergeNQubitGates optimizer calls off to cirq.drop_negligible_operations and cirq.drop_empty_moments ?
Also, the call sites calling MergeNQubitGates have been updated to call cirq.merge_k_qubit_unitaries and no tests fail right now. But to answer your specific question, cirq.merge_k_qubit_unitaries does not call cirq.drop_negligible_operations and cirq.drop_empty_moments by default.

Whoops, i mistook this for simplify_expectation_value_circuit that's after this.
