Websocket and `keepalive_ping()`

Hi!

When implementing a websocket system (like the suggestion from @ahopkins at https://gist.github.com/ahopkins/5b6d380560d8e9d49e25281ff964ed81), is the background task keepalive_ping() automatically implemented by Sanic, or should I need to run it myself?

I’d say it would be logical to have it automatically running, but there might be some constraints (or RFC recommandations, best practices, or protocol constraints) to not implement it automatically ?

Regardless of the response, it might be something important to have on the documentation ? (Either imlementing it and/or explaining why it isn’t implemented)
