Challenge 2 / 2

What's the purpose of prefixing service IDs with a dot (.)?

It marks the service as experimental, letting only daring developers use it.

Prefixing service IDs with a dot makes them hidden. They still work, but don't clutter the service list.

Dot-prefixed services are temporary and get deleted after one use.

Prefixing with a dot makes services run faster, kind of like a turbo boost.
