Yeah, I hope MCU has permanent character deaths or retirements ultimately. It's one thing that their 616 counterparts have always gotten cheated out of: a proper ending to their story. But the MCU versions at least as individual characters might. When the day comes that RDJ is done playing Iron Man, I don't want a recast, I want an ending.
You know what I want for Peter? To see him in high school for a movie, Then see him grow up and continue to be Spider-Man for a decade or so, including being married for the latter half or third of his arc and becoming a father toward the end. Always played by the same actor, aging with him. In the end he doesn't have to die, but maybe loses a leg or something and finally retires with his family. Miles then takes over, (maybe with the occasional Peter cameo) and they keep making Spider Man movies for another decade. And same thing, Miles can age and have a proper story.
Individual characters can this way have their progression and endings, but the MCU as a whole can keep chugging along and evolving.

And maybe ultimately hand the job over to Mayday Parker
