Neodymium is not on the “ban” list. Neodymium magnets are still the strongest with the highest bhmax. So no, “strong magnets” will not be affected. This makes the original premise wrong. Note that none of the articles cite any actual source, just vague mentions.
SmCo magnets are most heat resistant, and Dy/Tb doped neodymium magnets are the typical high temp magnets that would be used on a print bed for example. Sm, Dy, Tb are now restricted (dual use blah blah).
As far as the PRC lists are concerned, as of now hobbyists will not be affected when it comes to standard neodymium magnets.
