Hey Sean, would you please add some context to this bug, and possibly set the priority? Thanks!

The story is we introduced first-contentful-paint in bug 1518999, and the naming conflicted with our pre-existed internal FirstContentfulPaint metric. So we renamed our internal FirstContentfulPaint to FirstContentfulComposite in bug 1675640. And since TTI/TTFI were implemented before first-contentful-paint, so they are based on FirstContentfulComposite.

This bug intends to make TTI/TTFI to use first-contentful-paint instead of FirstContentfulComposite.
