In that case there are two ways feature could be activated.

1) Using a special symbol for `scroll-preserve-screen-position'.
   Setting it e.g. to 'always would preserve screen position of point
   for any scroll command, even those which would not move point out
   of the visible portion of the buffer.  The behavior you get when
   setting the variable to t would stay as is.

2) Using a new variable for activating the new feature,
   e.g. `scroll-preserve-screen-position-always'.

Personally I'd prefer the first approach because the current behavior
and the new one are mutually exclusive, so it doesn't make much sense
controlling them with two independent variables.
