It should be allowed for renaming the same import twice, with the same name. 

    // This should be possible
    private import gtk = gtk.Application;
    private import gtk = gtk.Window;

Please list what are the advantages an disadvantages of this proposal. (At
first sight I don't like it, but perhaps I am wrong).

The main advantage is that when you have libraries like the GtkD which I used
in the first post, you can put them all in one namespace. 

This way you don't get the redundancy of specifying the exact module name for
every call to a function, but you still keep your code clean and maintainable
by specifying what library a certain class/struct/object belongs to.

I can't really think of any. Obviously it can cause conflicts if you have two
matching symbols and you put them in the same module/namespace; but conflicts
are already possible as-is, and should be avoided.

How is this different from a package.d file?

You mean having a separate module publicly importing all the required modules? 

The difference would be that not a separate module would be needed for every
different set of includes possible. Obviously you could make one file simply
importing everything, but that'd just be an over-kill. When a module only uses
2 or 3 modules it's not worth importing every single one of them.
