Conversely, I find it really useful to block any notification from the get go.

Notifications are blocked by default.

No. If they were blocked you could only unblock them in the settings app.

They're only blocked when you don't allow them.

[ajscanlan]

If the app doesn't ask, they can't send them. They're opt-in.
