It is indeed a choice on our part to remove pure Ada05/95/83 support from the community release of the compiler.

That being said, 99% of Ada2005 project will work just fine in Ada2012 modes. So you can either don't specify any language version switches and the compiler will be in Ada2012 mode by default, or you can explicitly use the Ada2012 switch.
