It doesn't mean much. (Destiny)

Since we have been doing telescopic observations of planets, it's been there. We don't know how it fluctuates or how it dies. Just because it's getting smaller doesn't mean it will go away.

Furthermore, some historians claim this is a new red spot from the 1800s, and prior to this, there was a different spot visible for over a hundred years prior, and people just associated the two with each other.

Large storms continue to be created. For example, in 1997, a little red spot showed up and continues to grow larger.

It's unreasonable to assume that the GRS must diminish in our lifetimes or that it or a new red spot wouldn't be there in a thousand years.
