It would require a complete rewrite of most of the display engine
code. The Emacs display engine is based on the principle that point
should always be visible, so whenever it becomes invisible, Emacs
scrolls the window to make it visible again. The display code checks
this in many places, and they all will need to be changed in some, yet
unspecified, way.
Emacs provides the mark and "C-x C-x" as a way to jump between two
locations without requiring the feature you describe. If the purpose
of what you want is some other use case, I think it would be good to
have it described.
