Everything to do with reimplementing sudo, though.
But sudo has its share of CVEs as well (latest CVE-2025-32463), so perhaps a fresh look on the tool is warranted; perhaps some learnings have been taken from it.
I think if rust was used to replace other bits (say things like utilities like grep or whatever) instead of security vital things like sudo, there would be less complaints.
