• compatibility applauncher was dropped from admincentral 6.3 branch quite early
• check & remove leftovers of previous configurations (in ui-admincentral, or the compatibility layout, also the obsolete magnolia.property)
• admincentral-legacy depends on admincentral
• doesn't compile currently due to feature-toggle impl, & removal of older appLauncherLayout from module class
• currently no 6.3 branch of legacy module, but maybe it's easier to resolve if we create one
• we need RNs how to update to the new config location & modern layout
• 6.2.22 had all the messaging re: applauncher update ⇒ reuse 👍

Outcome: only one way to configure appLauncher
