It is a valid question While the abdication of Queen Beatrix isnt necessarily the best guidepost because the law on this sort of issue varies from country to country compare the Netherlands where the heir apparent succeeds to the UK where Edward VIII had to disqualify all his descendants if hed had any it might still provide a useful guidepost I do think Wikipedia can take some time to hash this out however because until the conclave elects the next pope its not an issue that would cause significant confusion
