The only little bug is if you resume a transfer of a file that is filled with zeros then the recipient will re-request blocks it already has (because they are zeros) so that parts of the file get sent twice (worst-case scenario). It is a bug, but a small one IMO that has never manifested in my reality (via issues or my own use). Happy to accept PRs to fix it though!
