It's just the sign the number of Pokemon was getting out of hand, and it had some design and spritework consequences. To this day, Gliscor is one of my least favorite Pokemon designs because of the horrible first impression his art render and sprite gave me. So boring, completely flat and symmetrical, which did the design no favors, and also, traced for the sprite. So fucking bad, they had to redo it for Platinum. As early as Gen 3's sprites not being animated till Emerald (and even then, it was just motion tweens) you could already tell the job of making so many sprites was turning into a monumental workload.
