[PureOS] policy for level of stability of PureOS stable

How stable is PureOS stable a.k.a. amber?

Which criteria for permitting new packages to get included?

Which criteria for permitting existing packages to get updated?

Do I just use my gut feeling?

Concretely, David Seaward wants ldh-gui-suite added, but makes sense to me to address this generally, eary on.
