Yes, basically it would be a way to make working with `EventTarget`s more consistent with other DOM APIs.

For example: the person who asked me for this said "I need to make a few requests and subscribe to a few events when the user navigates to a certain page in my SPA. I am already using an AbortController to abort all the pending requests if the user navigates away - it would be very useful to also unsubscribe from all events the same way essentially having one way to 'cleanup' "
