Society overall and human mind in particular have a great tool that handles that situation: forgetting. Stuff that is not in use is gradually getting forgotten. So if you do not update your project (because you abandoned it or because you are dead), then the project is getting useless and is gradually forgotten. Yes, you can put some effort into maintaining your digital project after your death, but it worth the overhead only in a very rare cases. Most of the time it's better to spend the effort on creating new project, than on maintaining someone else's digital project.
