I can still download or compile and install any binary I want. It only reminds me that this was done so and asks me to confirm. Isn't it?

Use `spctl --status` to see the status of Gatekeeper.

If Gatekeeper is enabled, the binaries you're downloading must have been signed by a valid developer ID. IIRC binaries you compile yourself get whitelisted automatically.
