Ok, definitions cleared. A few questions come to mind however:
A) don???t you think the best improvement in stability in one exercise comes from doing exactly that exercise, and any cross over effect would be secondary;
B) by progressing in the basic lifts here mentioned, stability is gained as a natural positive side product, without the need to actually focus on (or search for) stability in itself?
???provided any progression in load, regardless of exercise, is done in accordance with technical capacity.
So, for instance, I understand (and somewhat agree to) your rationale in having your athletes stick their landings. Nevertheless, don???t you also think a natural ???bounding-balance??? is efficiently created by just bounding till they feel the rhythm and balance in the movement? Regardless of how well they manage to stick their landings, they still have to learn how to mange their balance while moving.
I can definitely relate to a situation where an athlete has problems with his balance and thus must start over by first learning to ???stick???. But this would be on an incremental, case by case, basis, not a rule of thumb for everyone.
