These chat bots always hedge like that. They will never give you a straight answer, it's always "depending on version and build configuration and system configuration".
Investigate yourself. Read the documentation. Grep for brotli in the source. Don't blindly trust a chat bot when it says it "might happen in certain configurations".
I've noticed the newer frontier models are a lot better about this and are willing to give concrete answers, where before even in 90/10 scenarios they would always be wishy-washy espousing the "it depends on the circumstances" BS.
