8 months ago I think Voxels has the simplest system for attachment points I seen
You can drag an object to a general area / bone to attach to then fine tune the offset transform. This system can be improved by using sliders for the latter part. There is also a JSON export to download all the transforms. Example is here: https://github.com/M3-org/avatar-interop/blob/main/wearables/voxel_costumes/costume%233024.json
Can use CV_OG.vrm to test with https://github.com/madjin/cryptovoxels-avatars/tree/main/avatars
It's not fun to have to constantly switch between blender / unity to do basic editing of wearables, it'd be better if one could import a wearable that doesn't have any armature and then attach it somewhere in the editor. Maybe threejs editor can be forked / used for gizmo / hierarchy functionality: https://github.com/mrdoob/three.js/tree/master/editor
