User Agents are an increasingly unreliable mechanism for determining the compile target. Also, esnext does not mean the latest browsers, it means the latest spec version. The current versions of Safari and Firefox are missing support for some ES2019 features, let alone Firefox ESR or Safari for iOS. An esnext target is not connected to any real-world usage, it's purely a theoretical syntax level based on in-flight specification work. Ultimately, the browser implementors decide which JavaScript features ship and which don't.
