closes#10447
- Get helper message talks about the old API, but upgrading is the best way to solve the problem
- Had to create a way to add a custom message to a labs enabled helper to achieve this
closes#10114
* Members lab enabled to be always true behind developer experiments flag
* Members lab set to true for themes behind developer experiments flag
Note: This change uses hard-coded labs value for members based on enableDeveloperExperiments flag, ideal implementation for later is to pick those value from settings.
