That is the most annoying thing. People do not like "use" yet are not 
ready to face the consequences of their ideological choice. So they do a 
thing which combines disadvantages of both approaches.

That is cool.

scrambled and then use GPS' go-to-declaration to open the package.

P.S. GPS could have quick search in the project pane and have all Ada 
RTS packages there.
