It isn't even as bad as Dennis described it (I agree with him that it would be bad). Among supertournaments, there will also be Superbet (part of the Grand Chess Tour like Sinquefield Cup) and Norway Chess (where even Carlsen, who predicts/wants that classical chess will be "phased out", is likely to play). This year will also have the revival of Qatar Open (Carlsen already committed), in a way replacing Gibraltar like WR Chess Masters replaces Grenke Chess.
Maybe not noticed internationally, many top players also play in the German Bundesliga (also against "lesser GMs"): from this tournament Abdusattorov, Duda, Esipenko and Keymer (Aronian and Giri are on the Baden-Baden lineup but rarely play), other world-top players are Mamedyarov, Rapport and Vachier-Lagrave.
On the other hand, "national championship" might be the US perspective: in other countries, top players often skip their national championship as it isn't a supertournament and doesn't provide the conditions they normally ask and get.
