Future of Prometheus Agent, Scrape Manager and ServiceDiscovery

Introducing Prometheus Agent Mode, an Efficient and Cloud-Native Way for Metric Forwarding | Prometheus says Agent mode essentially moves the discovery, scraping and remote writing to a separate microservice.

What does this mean?

Breaking the current Prometheus Project into Agent, SD, Scraping, and good old standalone server?

Does this also mean, in the future users will install 3 microservices on k8s to deploy one lightweight monitoring agent?
