It always puzzles me why they chose the one distro without systemd to base this on and are now trying to add it themselves.

Also I have thoughts about this:

Move sudo to community
At present, sudo is in the main repository, which requires us to provide security support for 2 years. Upstream sudo does not provide an "LTS" lifecycle, so this requires either performing security upgrades during the maintenance lifecycle, or backporting security fixes by hand.
Benefit to Alpine
Prior to the creation of the security team, there was an unofficial preference to push doas as the preferred pivot tool for Alpine. This reinforces that messaging. Additionally, we do not have to support sudo for a 2 year lifecycle, since there are no LTS branches for it.

How often does sudo have security vulnerabilities that it's worth moving to a lesser used tool whose vulnerabilities are less likely to be discovered against your security team's wishes? What do all the other distros do?
