It's part of an overall trend. For example the gatekeeper security settings ux has slowly been removing options to run unsigned binaries bit by bit.

In 10.12 there is no obvious way on how to run unsigned binaries now. When you double click on an app multiple times, it refuses to run. If you go to security settings you cannot run the unsigned binary from there. You have to right click on the app and press open to get the old dialog that would allow you to run an unsigned binary like it's some sort of easter egg. In older versions you didn't have these restrictions.
