Sure there are scenarios where it doesn't really matter, but that is not everyone. Edge caching is great if resources can be shared. Sometimes resources are per-user. SPA's that involve dynamic per user content still have to load it to show the user anything interesting. Edge caching is definitely not 10ms for everyone. Depending on who you are targeting that could be a reasonable assumption, but it is definitely not true of the world at large.
