The slippery slope "fallacy" has been proven to be an effective tactic to shut down opposition to incremental enactment of unwanted policies and outcomes. In fact, I would argue that those proclaiming this as fallacious thinking are themselves are appealing to fallacious reasoning by simply declaring other outcomes as absurd. It also employs shaming tactics, where you use ridicule to suppress anyone who might see that the end outcomes are not so impossible as was implied by naysayers.
So it is possible to set a boundary that one does not cross in either direction without having a slippery slope where the boundary keeps moving
But the reality in most cases of modern politics is that the politicians intend to change the boundary in the future so such a slippery slope is not a fallacy or it is a fallacy that happens to be true in that case but is called a fallacy because it is not true in all cases
The fallacy fallacy is to assume a fallacy can never be true
