I don't see that.

a) They might be editable (and even authored by the user), but it's 
pretty likely that they are not the part of the current project. Which 
can be Emacs (which doesn't depend on any load-path directories outside 
of its tree; it just helps them work).

b) We have no project files to determine the actual dependencies of the 
little Elisp package you're working on, and figure out which projects 
it's tightly coupled to.

"editable" and "owned by the user" is irrelevant. The docstring doesn't 
mention either of those conditions.

Not if you only take one word from the whole docstring. It says 
"directory ... contents meant to be edited together".

Which, yes, if impossible to determine for load-path, which is why it 
goes into library-roots.

But it's possible to answer that question in other languages and 
configurations.
