As far as expectations for 2 above, in my experience, teams really love having a completely separate environment per PR. Gitlab has done this on top of Kubernetes using a dynamic domain such as <truncated-branch-name>-review-app.domain.com. This gives QA and stakeholders the ability to easily review/signoff on changes prior to going live and not getting bottlenecked by a small number of QA/UAT environments. This becomes particularly helpful as the engineering team scales up.
