Yup, I guess not. But if I was on the product team, the customers and director ate the bosses. And on it goes up to the CEO, where the board and shareholders are the boss.
If I can justify the change, we'll do it. That's close enough for me. And I did do a POC w/ Rust and could've switched one service over, but I campaigned against myself since we got good enough perf w/ Python (numpy + numba) and I was the only one who wanted it. That has changed, so I might try again with another service (prob our gateway, we have 3 and they all kinda suck).
I'll have to check out Deno again. I remember looking at it (or something like it) a couple years ago when first announced on Reddit.
