First deployment of Growth features to English Wikipedia will first happen only to 2 % of the newcomers. Before doing so, @MMiller_WMF wants to show welcome survey only to users with homepage enabled.
In this task, we want to add a config variable WelcomeSurveyEnableWithHomepage. If this variable is true, welcome survey will show the welcomesurvey to all users with homepage enabled, and no survey to the rest of them.
This is similar to T284127: Make it possible to deploy welcomesurvey to % of users that's not divisible by 10.
