My understanding is that this line of thoughts gave us Extension
Templates which are templates, not extensions.

My main question when thinking that way is:

- how to update from a version to another one?

The point about extensions is that we separate the author who maintains
the upgrade scripts from the DBA who operates the upgrades. It seems to
me it's important to keep that property.
