Per new performance recommendations by Mr. Paul Irish, it’s valuable to know what it being served in the first 14KB of content.

Perhaps best served as another vertical bar (like the blue DOMContentLoaded or red onload) on the Network tab or a subtle highlight on the first 14KB in the Elements tab.

This seems arbitrary and not something that we can actually determine, given parallel parsing and pipelined networking.
