That's a bit extreme, but overall not a bad modelling practice. This is especially true in cases where persons other than the CAD modeler make most of the design decisions.
With new designs, I normally make one or two "control line" sketches. For instance, the main profile of an extruded hinge will be a stand-alone sketch. The first extrude feature's sketch will reference the control line sketch using "Convert Entities". Later features reference the control line sketches instead of model edges whenever possible.
This may sound like a pain in the arse, but it saves a lot of trouble in the long run. I find it's easier to manage changes in models when they are constructed in this fashion.

You think that is extreme check this out!
Now that you have those 3 driving sketches (top, front & write) you can create a design table that drives your driving sketches.
In other words when you want to change something you look only in one place your design table.

DT drive Dimensions, so if your sketches are controlled by dimensions, then the answer would be yes.

They can be added, but they can't be changed.
