Then please also provide a convenience package that can be downloaded by 
people building Qt from source on Windows.

The current solution (and the proposed additional repository) have the 
advantage that people don't have to search the web for the binary 
package with the right version, potentially grabbing some out of date 
stuff, resulting in strange bug reports with the component "Build System".
