In comparison to DOTween's corresponding methods, VRCTween.Tween(Local)Rotation and Tween(Local)Path skips RotateMode/PathMode parameters.

With original DOTween we can tweak subtle behavior of rotation amount and look-at direction respectively.

Current VRCTween does not have them so we have to use Virtual Tweens to interpolate in that way (e.g. rotate Transform beyond 360°).

Are they intentionally omitted? If so, what is the reason for that, for performance or API complexity?

It may make VRCTween more attractive to export these types and take as parameters (in last position).
