Thanks for the heads up, I hadn't realised that Static Hermes has the "sane subset" idea underpinning it! I had just thought it's an (somewhat) AoT JS compiler, like a mix between Porffor and V8. I'll have to look into their subsetting and indeed, match theirs as much as possible. Especially if they have written custom specification patches / versions. Thank you so much <3
