Config Service Watch for Updates

Why do config services expose a long-poll or watch stream in addition to plain GET?
Options
  1. 1Watch streams guarantee the cached config is never stale by even a single millisecond
  2. 2Plain GET responses cannot be served from a cache unless a watch stream exists
  3. 3Watch streams remove the need to version config documents at all across environments
  4. 4Clients learn about config changes promptly without busy polling every instance at high frequency
