same issue

Sybren A. Stüvel (sybren) claimed this task.

I checked with the UI team, and this is working as designed. When you pin in the mesh panel, you pin the mesh itself. The vertex groups and shape keys are defined on the object, so they disappear. When you pin from the modifiers tab, you pin the object, so you still have access to its mesh. The same is true for lamps, cameras, materials, etc.
