First, C3P0 in Empire Strikes back on Cloud City. I know it's not a real death, but I mean come on he's a droid and was never really alive.
On Bobba Fett, Star Wars is a Science Fantasy Space Opera. Bobba Fett had a classic Soap Opra death. If it's off screen or a closed casket funeral they can be brought back later. Also he got out of the pit long after they had left the planet so it would have slowed the movie down.
And Star Wars doesn't do the after credit clips like other modern movies. They were the one of the first to do the 5+ minute after movie credits at the time.
