I think it's more subpackages such as -dev, -lib and -doc variants. These are defined as part of the parent package but count as distinct packages.
Anyway, this is all besides the point I was trying to make which is that I don't see why I should use _yet another_ software distribution that has 1% of the amount of packages found in a mature distribution that already has frequent automatic updates and bleeding-edge software revisions.
You definitely don't need to use Wolfi! But I would say, if you run containers you might want to check out Chainguard Images: https://github.com/chainguard-images/images
