Ask HN: Is there a way to keep phone contacts from seeing that you're on Signal?

I think its a bit annoying that there are people who get notified and vice-versa that someone is on Signal. If there is any way to avoid this, that would be great, otherwise what other services are out there that are similar but don't let the world know you exist without you letting them know first?
