It's not an unreasonable task for a small team of skilled engineers who know V8 in depth, the kind that FB can and probably has recruited. If they're taking most of what V8 learned over the years into account, they'll know what to prioritize and what to not to.

V8 has to choose when interpret and when to compile, when to load things into memory, when to garbage-collect, etc. and they do so keeping in mind it is running javascript from the internet, for any kind of application, on any kind of device. Hermes can make many more assumptions and so the engineers, even if they built something very similar to V8, can probably dial the knobs much more differently to optimize for what Hermes cares about.
