I'm not sure what you mean.  You don't have to know what default
conrol points values are to be able to write a call to \shape.  It's
shape's business to get to the default values and alter them when
LilyPond is ran.

So, the workflow is:
- user adds a slur
- user previews Lilypond output
- user decides that control points should be adjusted, for example
first control point should be moved up by 1 ss
- user writes \shape #'((0 . 1)(0 . 0)(0 . 0)(0 . 0)) Something
- when Lily is ran next time, curve will be changed.
