Christian, your desire for a single MSI is well known, and repeatedly stating that desire is far more likely to raise ire rather than spur change.  No, you did not need to include "ceterum censeo".

The installer system that Steve created for us has many features that I and many others would be very sad to see disappear again, and which cannot be supported by a single MSI distribution.  In particular, selecting which components to install and only downloading those components is a wonderful feature for anyone with a low-bandwidth or metered internet connection.

If the current installer is unusable to you, feel free to forward-port the old 3.4 installer system and create your own installers.  Alternately, feel free to provide patches to resolve this or any other issues you have with the current installer.
