The only functionality it has is
> m_domTimerAlignmentInterval = m_domTimerAlignmentIntervalIncreaseLimit;
though there is a comment suggesting it would update visibility state as well (that's no longer true).
I can't immediately see what we do for non-"prerender" hidden pages, but presumably they would also throttle the timer interval?
Blame suggests you might remember Tim though it's been a decade or so.

It seems this is not a prerender feature, but part of "page visibility" which used to have a "prerender" state that we stopped exposing at some point and now it's only visible (harhar) through maximum throttling. Leaving this as-is seems fine.
