It indicates that the callers of find_shared_symref() to see if "is this branch being actively used by checked out, bisected, or rebased, and I shouldn't touch it?" need to know more than what find_shared_symref() interface gives them---namely, "can I repoint it to a different commit?" and "can I make it disappear?" are different conditions they need to be able to learn. Until that distinction becomes expressible, I am actually OK with forbidding both operations, i.e. while a branch is being bisected elsewhere, we should be able to update its tip to point at a different commit, but it is OK to forbid that because we cannot allow the branch be renamed away or removed. Thanks.
