Important: #92870 - Always use Fluid based page module

See forge#92870

Description

With forge#90348 a completely rewritten page module has been added as a replacement for the PageLayoutView. As this replacement is stable enough, the feature toggle to switch between the different implementations has been removed.

Impact

The feature fluidBasedPageModule is now always enabled. Extension authors can therefore remove any check regarding this feature as it will always return true.
