I’m still open to it and thinking about it actually. I will explore if it’s possible to eliminate the large losses on common patterns and if it turns out it is then it’s a no brainer.
Going forward this and the extended operators + large pattern perf will hopefully be a strong selling point to gain more traction
I would argue that hardened mode should be default though, similar to how siphash is the default hashing function in Rust hash maps. Faster mode should be opt in if the user is confident that the supplied data is nonmalicious and they need the speed up.
