Not everything is serialized. (at leas really serialized to a stream)
replacing panels is pretty cheap to do the only thing is it keeps a reference to the previous panel it its versionmanager of the page
(as long as the page is in the page map (10) or the you have 10 versions of youre page. (the olders page or page version will be discarded)
So in the end it is exactly the same as visible. (you als keep a reference)

Yep. Either that, or - if you don't want to use pages you can use
panels, and replace one for the other. Or if you think replacing is
too expensive (everything that is replaced is serialized and saved in
order to support the back button by default), place all panels you
want and switch the visible property.
