This would be the same as a football championship, starting with the previous year's winner with negative points. Something that doesn't make sense and doesn't happen.
You know, actually, this
does happen

At least in Romania (I did not have time to search for the subject if it happened in other countries too). But in Romania, during past years, multiple teams demoted to second league started with a negative number of points. This happened for same reason: during the previous year, the teams did not pay their players. They made complaints to the Football League and the committee which judged these cases always gave same decision: the club has a given amount of time to pay the player(s), otherwise a number of points will be deducted from the points the team earned. At first offense they took, usually 3 points from the team's earned points. Then, if the team still did not pay after the given amount of time, they applied a second penalty -- maybe 3 points again or maybe more. And so on.
This article describes the case of Astra Giurgiu, ex-championship winner of Romanian League, which, after being demoted in League 2, started the new year from -6 points.
Gaz Metan Medias, another case of Romanian championship,
was sanctioned last year with 50 points, reaching a score of -27 points.
Articles are in Romanian, but this is less important. The idea is that it may happen

Thanks for sharing this information.
But this happens, not only in Romania, it is in almost all championships where there is some illegality on the part of the clubs. Now, the penalty is not because they won or dropped, but because they didn't pay players or committed some fraud.
And that's what I'm talking about, penalizing for having won doesn't make sense.
