Because the shape of a wheel has a much smaller effect on it than both height matchups and spin direction. Flame was only noted for effectiveness because it had good stamina - the destabilisation people went on about was due to the height, and LTSC completely outclassed flame etc "destabiliser" combos - which were actually just an error, in the end - while SF may make them seem different at first, it never did allow them to KO anything reliably or take hits any better than WD, otherwise it would probably still be around, and furthermore, that is KOing and Defending, not destabilizing, so it doesn't "count".
LDrago mainly used the opposite spin+aggressive movement method combined in addition to low height to destabilise opponents. It had enough aggression at the time to be able to KO most things it couldn't outspin, which prevented it being straight outclassed by LTSC's. That type of combo is still around, actually. MF LDD BD145MF and the like were some of the best answers to E230 at least when it was first introduced, because they destabilised it.
Basically, what we called destabilisers weren't ever a proper type of combo, they were just bad LTSC's.
Destabilization is a thing and some parts do it slightly better than others, but it basically only makes a difference if one of the other causes is present - having a destabilising top side doesn't matter unless you get it under an opponent, being able to smash opponents downwards doesn't matter if you're taller.
