Maybe make this reload the page with ?gk_debug&gk_enable=react_enable_scheduling_profiler instead?

Ooh, that's an interesting suggestion. Guess we could also enable the react_enable_profile_timer GK too and remove the "profiling build" instruction entirely. Let me think about that!

Okay I think I might pass on this for now for a few reasons:

  1. Facebook internal build doesn't necessarily mean you're viewing a Facebook website (that supports URL params like gk_debug).
  2. I don't think there's a way to detect if the user has already loaded a build with the right GKs (and avoid showing them a reload button unnecessarily).
