ok, so it's not really a feature as I see it, but here is the problem :
sometimes, it's easier to have all your animations on a single spine project, with all your animations there.
But in this case, only 1 animator can work on this file.
so if you want to use a VCS to share your animations, like when one guy working on some animations and another one on other animations, it's not currently possible because the project is one single file
an interesting example of that is the xfl file format from flash, which is a non compressed, xml based file format. so all your clips, and stuff are stored in multiple files.
Do you think it would be something you would like to do ?
