System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 535.98

Blender Version
Broken: version: 3.5.1, branch: blender-v3.5-release, commit date: 2023-04-24 18:11, hash: e1ccd9d4a1d3
Worked: (newest version of Blender that worked as expected)

Short description of error
When sculpting on a curves hair object, the Density brush doesn't produce exact symmetry of the hair strands.

Exact steps for others to reproduce the error
Create a new Blender scene. Load in any object with local X-symmetry.
Add a curves object onto it.
Go into sculpting mode, select the Density brush, and select X-mirror.

When sculpting, the larger brush positions are mirrored, but the individual strands are not symmetrical.

This behavior is likely intended, and certainly helpful in certain situations when the artist wants to keep variety between the individual strands on each side. But once combing starts, it's incredibly frustrating to get both sides to look the same. Usually requiring that symmetry is turned off, and each side styled individually. This is a massive time loss and produces ugly results.

This is probably more of a feature request than a bug report, as I would love for this behavior to be toggleable.
Make a setting that produces the current results, and one that mirrors the strands exactly.

I am aware that the exact mirroring would likely create problems with the density resolution at the center line of the object, but I would be absolutely okay with resolution artifacts there, if that problem can't be solved. Just a proper grooming workflow would be amazing to have!
