My preference here would be not to re-introduce this upstream, since it's dead code as far as upstream is concerned. I actually think that Folly's approach is quite neat for a hack. It uses low-level functions that are unlikely to change in tricky ways to achieve its goal, and in addition it would turn a "merge conflict" of the kind we had here into a compilation error instead of a potentially silent performance regression. All in all, I believe that this is probably a superior solution to just relying on the internal name.

WDYT?
