I fully agree. The extension infrastructure should provide basic support
for upgrades, not every kind of bell and whistle one could possible think of.

The bells and whistles can then be provided by the system used to *build* the
extension. Not only does this keep the core infrastructure manageable, it also
allows different tools to generate the update scripts to exist, each catering
to the needs of different kinds of extensions.
