Blender Version
2.79b

in

class bpy.types.Bone(bpy_struct)
parent_recursive - A list of parents, starting with the immediate parent (readonly)
children_recursive - A list of all children from this bone. (readonly)

there are inconsistent returns depending on the 3d view mode.

In edit mode, children_recursive returns a list of editbones.
In object mode, children_recursive returns a list of bones.

this makes sense so far. now for the inconsistency:

In edit mode AND object mode, parent_recursive returns a list of bones.
parent_recursive does not return a list of edit bones while in edit mode.

does it make much more sense to have a list of edit bones return while in edit mode?

Could you show a test-case of this happening, a quick test here shows this to work as expected in 2.79b and 2.80.

>>> bpy.context.object.data.edit_bones[-1].parent_recursive

[bpy.data.armatures['Armature']...EditBone, bpy.data.armatures['Armature']...EditBone]

You need to access edit bones from the armature, eg:

bpy.data.armatures['Armature'].edit_bones['Bone.009'].parent_recursive

You need to access edit bones from the armature, eg: ``` bpy.data.armatures['Armature'].edit_bones['Bone.009'].parent_recursive ```
