Thank you for the feature request!

For example, the following component moves particles on Update. It works.

using UnityEngine;

[ExecuteAlways]
[RequireComponent(typeof(ParticleSystem))]
public class ParticleMovement : MonoBehaviour
{
    public ParticleSystem m_ParticleSystem;
    public Vector3 m_Move = Vector3.zero;

    private static readonly ParticleSystem.Particle[] s_Particles = new ParticleSystem.Particle[1024];

    private void Update()
    {
        if (!m_ParticleSystem || !m_ParticleSystem.IsAlive()) return;

        var count = m_ParticleSystem.particleCount;
        m_ParticleSystem.GetParticles(s_Particles);

        for (var i = 0; i < count; i++)
        {
            s_Particles[i].position += m_Move * Time.deltaTime;
        }

        m_ParticleSystem.SetParticles(s_Particles, count);
    }
}

Thanks, I'll try it out. I only tried it from a component that was not attached to the same game object as the particle system, but a parent of it.
