Seems like this has been our intent but was not updated that much recently.

The makecd handler checks if those tools are installed, sure, but it actually

This makes it easier to track and understand changes using Git

Sort Suggests lexically while I'm at it.

This makes it clear what package(s) one must install in order to use any given

Now that there's some removal of increments for old fulls, we can keep fulls for a longer time, for instance 1Y which becomes default
