Motivation
In addition to being able to roll out feature flags gradually, it would be nice if we could have flags that are only on if explicitly enabled. That allows us to hide under development functionality that's not ready even for beta testers.
This PR adds support for under development flags.
Implementation
Started considering -1 as the indication that a flag is under development. If the value is -1, that flag is not enabled based on the
all
setting and can only be turned on by explicitly opting in.Automated Tests
Added a test.
