Yes. Not necessarily with the mouse. You can call a lisp function to commute to a new tab. In firefox you can commute to the next tab using C-PgDn .
Every time when you commute to a tab, the lisp function associated to the 'show event is called.

In graphical systems, like GTK, there is the concept of 'callback.
Sure. But any such function could be used in another context as well.

As mentioned before, we could easily add menu- or toolbar items which
stand for "saving the current window configuration" or "restoring a
previously saved window configuration". I can neither see why such
actions should be exclusively tied to tabs nor why tabs are very suited
Probably yes. But a toolbar button is not a tab. And do not forget that toolbar does not exist in console.
In mozilla you can install lots of kind of bars. And there is no doubt that the tabs are still useful. In mozilla the tabs are used for current-open pages.
