Would its definition add the VC root to the list returned by 
project-search-path-function?

There is no elisp project backend. Just an elisp-specific value of 
project-search-path-function.

Which obviously omits project-roots and project-ignores.

project-roots sounds better: it reflects each element being a "proper" 
project, hints at the presence of project files inside, and also implies 
"read-write".

Any elements of search-path outside of project-root can be considered 
read-only.
