IMO this is superfluous. Modders will find use-cases for this parameter fast enough.

What can be used? `set_rotation` if so, then it's superfluous to state it here as well.

@SmallJoker Should this if-else block be restored as well?

If it's only for `automatic_rotate`, please re-add the check to skip this part when it's not needed. -> `if (std::fabs(m_prop.automatic_rotate) > 0.001) { ....`

You already checked for `getParent()` with `if`.

When `getParent() == nullptr`, this code can be skipped because `local_rot.Y` keeps its old value.
