Alexander Meißner (Lichtso) added a comment to T60930: Cant set particles[0].hair_keys[-1].co = Vector((0,0,3)).

Does not work for me it seems.
It does not matter how much I switch between object, particle and edit modes.

The problem goes far deeper:
Depsgraph copies every object and all their parts including ParticleSystemModifierData.
The copy of ParticleSystemModifierData is used in deformVerts and gets a mesh_final assigned.
However, the rna_ParticleHairKey_location_object_info looks in the original object for the ParticleSystemModifierData and that one never gets a mesh_final.
rna_ParticleHairKey_location_object_info also does a linear search over all hairs for every access to a HairKey which is extremely inefficient.
