In these days I'm starting to move some projects from Delphi 7 to Delphi 2006. Therefore I started to install all the required libraries in Delphi 2006. And I found out that many libraries don't use packages properly. Beyond the runtime/designtime issue, many libraries don't set the options properly to share the same code among different versions of Delphi. Once I was used to keep different copies of each library in each Delphi folders, in a folder named "3rd".
