Yes.  You *have to* do it like that, the shortcut is not an option,
because without an extension update script there is no way to
upgrade an existing installation to the new definition.  Basically,
once we ship a given release of an extension, that script is frozen
in amber.

I haven't heard any further bikeshedding on the argument names,
so I'll move forward with committing this soon.
