5949b796f0Short description of error
When i am trying to use rotation with paths/strands it just do not work at all.
I know that new hair system is in development and probably this issue will not be fixed for current system.
But I hope, it will fixed at least for next one. Perhaps as «initial normal distortion» or something like that.

Open a file, switch rendering type to path.
hairRotation.blend

Changed status from 'Needs Triage' to: 'Confirmed'
I can confirm the problem. However I am not sure if it is a bug, since it has always worked like this.
But if it is a limitation, the interface could indicate this by graying out that property.
@mano-wii I am not sure, it is limitation. I mean it is possible technically as initial normal tilt (hairs follow face normals)
But it looks like all hair bending and grooming based on vector displacement without normals/rotations/rolls.
But Instances have rotations.
