I would add that we should continue to add Prometheus annotations though if prometheus.enable is true. Or, maybe a new value with a more intent-revealing name that toggles the annotations.

Ok sounds good. I'll split these up into two different PRs, the first for grafana, the second for prometheus. The grafana removal is much more straightforward. There are some different choices that could be made on the prometheus side of things for implementing scrape config (labels, servicemonitors, etc.), as well as where to draw the line for what stays in.
