How many of those producers are actually involved with the making of the show? Probably half or less. The four that are writers to be sure. Stewart, Goldsman and Kurtzman probably. Roddenberry and Roth, probably not. They're EPs because their production company is involved. And part of today's reality is it takes multiple production companies to get shows made. Picard has five. TNG had one. Some had producer credits for just a few episodes usually ones they directed or wrote.
Not credits are created egual.
