This would have eliminated the need for drones to be retrieved or the seemingly necessary suspension of disbelief, seeing as how everyone fighting Beck (and viewers) would have already known his big secret. The best way that Mysterio could have come back for Spider-Man: No Way Home would have been as a variant from another universe who actually had powers to rival Strange's.

While that's fine for one film, it does create problems for future appearances (as exciting as it could have looked). Basically, the MCU turned Mysterio into a one-trick pony.

This was just before the villain died, doctoring footage to make himself look like the hero and Parker the villain. In Spider-Man: No Way Home , Peter Parker accidentally breaks a spell cast by Doctor Strange that was going to make everyone forget he was Spider-Man after Mysterio exposed his identity to the world.
