Subscribers In The Night... Shush, There Sleeping...

I disagree with this - I have things set up to sent me notifications ALWAYS. If it gets annoying, you can have a gmail filter auto-archive them. But there are plenty of times someone will ask about a collab, or say something, and you want to know when they subscribed. Then it's simply a matter of checking your email!

Guess it depends on your type of channel. I personally have no need to check when someone has subscribed etc.
