The article states, in regard to possible new age limit changes:
“Besides a possible ISU Council proposal to be put on the agenda of the 2021 Congress, some ISU member federations have also signalled their intention to do so. Consequently, there will most likely be a debate on the issue during the 2021 Congress.”
So this is more than just a revisit of the original Dutch proposal, which was put together very quickly before the last Congress. We can assume new proposals will probably be crafted more carefully, with input from different stakeholders. Also, there will be time to lobby for and debate the proposals prior to the Congress, which wasn't the case at the last Congress.
I think these proposals are being spurred not only by Alexandrovskaya's case, but also by the many other abuse cases that have come to light over the past couple years and that have clearly shown how vulnerable younger athletes are to the power imbalances and pressures of the sport. Although no age minimum will prevent all abuses, a 2-year increase in the minimum age could make a real difference in some athletes' ability to handle the pressures of the sport, as well as make a real difference in how hard they are pushed by coaches, et al, at very young ages.
I would 100% support this change.
