Yesterday I made the monthly update following trunk of my SqueakRosCore
and notice we don't have Smalltalk unloadAllKnownPackages now

My idea is
 "Unload packages which can be reloaded."
  #( 'ReleaseBuilder' 'ScriptLoader'
  '311Deprecated' '39Deprecated'
  'Universes' 'SMLoader' 'SMBase' 'Installer-Core'
  'VersionNumberTests' 'VersionNumber'
  'Services-Base' 'PreferenceBrowser' 'Nebraska'
  'ToolBuilder-MVC' 'ST80'
  'CollectionsTests' 'GraphicsTests' 'KernelTests'  'MorphicTests'
  'MultilingualTests' 'NetworkTests' 'ToolsTests' 'TraitsTests'
  'SystemChangeNotification-Tests' 'FlexibleVocabularies'
  'EToys' 'Protocols' 'XML-Parser' 'Tests' 'SUnitGUI'
  'Help-Squeak' 'HelpSystem' 'SystemReporter' 'GetText' 'Environments'
 ) do: [:pkgName| 
   (MCPackage named: pkgName) unload.
   MCMcmUpdater disableUpdatesOfPackage: pkgName.
 "Traits use custom unload"
  at: #Trait
  ifPresent: [ : aClass | aClass unloadTraits ]

And we get rid of more packages.
 Of course we must be careful of go back to previous version of methods
concerningto Environments
