I don't see how this is related to the issue at hand.  All I'm saying
is that a package, including its key bindings, shouldn't be loaded
until some of its feature is invoked.  Therefore, the best place for a
package's keybindings is in the package itself.  What you describe
seems to fit this principle.

We could make the keybindings autoloaded without having them defined
them when the package loads, couldn't we?  By having the define-key on
the same line as the autoload cookie, like bookmark.el does.
