hdiutil is deprecated in the macOS 27 beta in favour of diskutil image

Sources: Lapcat Software write-up, HN discussion
Summary: The macOS 27 beta deprecates hdiutil and points to diskutil image as the replacement. The replacement drops options including -puppetstrings and -scrub, and it does not prompt for authentication on root-owned files.
Why it matters: Scripts and applications that shell out to hdiutil need review before macOS 27 ships, because the replacement is not option-compatible.
