In the comics, Madame Web was (originally) an old lady who basically saw the future and provided occasionally highly cryptic and generally useless (but super geek friendly) info to Spidey. In a big spider book crossover that is likely close to Across the Spider-Verse, she dies and one of the many spider women who aren’t Spider Woman instead takes over. While she’s slightly more active, she’s certainly not out saving the day. Spider-Man dominates his world…unlike some characters, everything tends to almost literally circulate around him unless they are heroes in their own right.
An entire catalog of Spider people to use and they pick Spider-Man’s astrologer? I would have preferred a movie just about daily life at the Daily Bugle. Think of it - 2 hours of J.K. Simmons. I’ll buy the ticket now.
