OpenBSD became concerned about sudo's codebase some time ago, and replaced it with the conceptually much simpler doas, which achives about 95% of what sudo does in real world usage.
I've heard of doas sometimes and it's much simpler than sudo, but it's powerful. Doas has two non-official port for Linux[0][1], but it would be great if someone developed an official tool like doas for Linux.
