--- Comment #3 from Michael[tm] Smith <mike at w3.org> ---
See the https://volument.com/blog/sendbeacon-is-broken#comments comments discussion for some real-world pain points developers are hitting due to this. (So that not only do we need to make developers aware that they shouldn’t be trying to use unload/onunload with sendBeacon(), and that they instead need to  visibilitychange — but *also* need to check pagehide (because we don’t yet have visibilitychange working interoperably for them across the web platform).
