The submodule doesn't know it's a submodule though, so the point of view
"I (as a submodule)" only happens rarely in the real world?
I have a library in mind when talking about submodules. And the libraries
maintainer may not care if their library is used as a submodule or just
"make install"ed or just put somewhere in the filesystem
Usually submodules are only interesting from the superprojects point of view,
like "I want to upgrade libfoo now, so I make a commit changing the gitlink
of the submodule to point at that tag/commit"
That's why I found the presented perspective a bit strange.
