steakhal added a comment.

If the inner pointer participates in a branch condition guarding the dereference, that memory region is gotta be important, right? So, we should mark it so.
A BugreportVisitor could easily transfer the information about the fact that the dereference was guarded by that particular branch condition - and marking the InnerPointerVal (MemRegion) important.

This way the NoteTag for the `get()` could emit the warning.

The other approach, you @RedDocMD proposed about checking the constraint for the inner pointer, seems somewhat odd to me.
It could work, but I think the visitor is cleaner.
