And now you're just outright lying. They explain directly in the updated paper why they changed things around - something that was already addressed in one of the articles I linked you to. Either you didn't bother to read it, or as I said before, you are a liar.

This position paper addresses vegetarian dietary patterns in adults aged 18 years or older who are not pregnant or lactating. Facilitating vegetarian dietary patterns in individuals younger than age 18 years and/or for those pregnant or lactating requires specific guidance that considers how vegetarian dietary patterns may influence these crucial stages of growth and development and is outside the scope of this position paper. The target audience for this article is RDNs, NDTRs, and other health care practitioners.

Those topics are literally just outside the scope of that particular paper. There's nothing about the paper itself, or any other resource on any of their other websites to suggest it means they've changed their position. From their position paper on nutrition in child care:

Some children may also require dietary modifications for certain cultural or religious preferences, including vegetarian diets,4 which may also have added benefits. A recent study of one child-care center in South Carolina found that adding vegetarian meals to the menu improved the nutrient content of foods provided while keeping total energy, saturated fat, sodium, and cholesterol relatively low.

And from another of their articles, reviewed on June 5th 2024:

A well-planned vegetarian or vegan diet can meet the nutrient needs of people during all stages of life, including pregnancy, lactation and childhood, as well as for those who participate in competitive sports. It's just about making sure you get the nutrients you need. Fortified foods and beverages can help to increase the intake of certain nutrients. For nutrients that are primarily found in animal foods, like vitamin B12, or when nutrient requirements increase during certain life stages, a supplement may be needed. During pregnancy, for example, more iron is needed, but iron is not absorbed as well from plant-based sources. Pregnant individuals should eat plenty of iron-rich foods, plus a source of vitamin C to help increase absorption, and discuss the possible need for a supplement with their health care provider. Try these iron and vitamin C combinations: beans and salsa, broccoli and tofu, black-eyed peas and collard greens. For infants, children and adolescents, a well-planned vegetarian diet can promote normal growth. Calorie and nutrient needs typically can be fulfilled if the diet provides enough calories and diversity of foods. Incorporating fortified foods and beverages and/or supplements may be needed in order to get the recommended amount of certain nutrients. And while most competitive athletes require increased energy, protein and nutrient needs for optimal performance, there's no reason they can't get everything they need nutritionally from plant sources. All it takes is a little carefulness with menu planning.
