True, the issue itself does not mention third-party tools directly. However, the underlying concern is still relevant. The fact that OpenZFS does not yet support safe resizing or shifting of partitions, even when done manually, means that any external tool performing such actions without deep knowledge of ZFS internals introduces risk.
Tools like GParted operate outside of ZFS’s control and are not ZFS-aware. So while not explicitly referenced in that issue, the implications are clear: modifying ZFS partitions without native tooling or support carries potential consequences.
The absence of direct mention does not equate to safety. It is still best to caution users when the filesystem's own maintainers highlight unresolved edge cases and undefined behavior around pool layout changes.
