But, on that point, it's not really necessary to tie Spider-Man with other Marvel characters outside of a few easter eggs let alone make his entire identity as a hero so dependent on another character when such a relationship does not exist in the comics. An MCU Spider-Man could have been equally as successful if they had just referenced events from the other films in the MCU. It's kind of analogous to a scenario where, when finally adapting the Fantastic Four for the MCU, they also choose to say that Reed Richards got all of his ideas for his inventions from Tony Stark. Of course, Reed Richards is a famed scientist who, traditionally, is the smartest man in the Marvel Universe. It would be a shame to cast him in the shadow of another character.
