There's a couple of instances where `Promise<void>` is still there, those are the exceptions, for example functions that explicitely return a `Promise` object or functions that return the promise from another function call without any `await` statement. used this one-liner to automatically remove everything: ```bash grep -rli 'promise<void>' | xargs sed -i 's/: Promise<void>//g ```
