cirq.optimizers.EjectPhasedPaulis(
    tolerance: float = 1e-08,
    eject_parameterized: bool = False
) -> None

As the gates get pushed, they may absorb Z gates, cancel against other X, Y, or PhasedX gates with exponent=1, get merged into measurements (as output bit flips), and cause phase kickback operations across CZs (which can then be removed by the EjectZ optimization).
