Not counting the redesign, there haven't been "sparkly" features. Sparkly features are the kinds of things the old management used to let engineers have free reign to implement.
Github pre-Microsoft was rudderless. They were more prone to implementing silly 3d model diff tools and things instead of supporting enterprise features or building powerful CI/CD tools and automation.
Many of my projects have a fixed scope and thus are 'done' at some point. If you develop like this, CI/CD is rarely worth the effort. Its better suited for projects that suffer from scope creep or regular upstream breakages.

New Github is on the right track.
