Yeah I thought so too. Though idk how integral they could make him to their story given that the 90s show is a Disney/Marvel owned property and not a Sony one. Regardless, I don't think a scene in Beyond of Barnes' Spider-man coming to help Miles necessarily precludes a '98 show. Though they probably wouldn't be able to directly continue the 90s plot in the movie and just leave it as a version of Spider-man who has experience with the multiverse.
