This description reminds how next-error works in a similar way.
By default, it uses the global value of the last navigation -
in project.el it could use default-directory by default.
But like a buffer can override next-error navigation,
project.el should allow a buffer to set a buffer-local value
to define its project like your project-find-functions.
