I assumed they would have the sense to let Spidey be his own man in the very next film though. I don't think we needed to have him exit the MCU to have that happen. Far From Home had to show him mourning Tony Stark since it was the very first film taking place after Tony died but I'm positive they would have embarked on a more traditional Spiderman from there on. They has a young actor who everyone loves in the role - if anyone could become the new beacon of the MCU it was Tom Holland who has charisma beyond his years. He could have had a great long-running arc as Spiderman and could have participated in any future teamups still.
Even if he's contractually obliged to hang on, I can now seem him leaving the role at the earliest opportunity and Sony will reboot back to square one yet again.
Yep. "New Tony Stark" is only in reference to becoming the new face of the MCU and duh, of course he should have that job, he's freaking Spider-Man. Who else should it be, Professor Hulk? lol
