I don't think it's okay, no.  But I don't think project.el offers
constructors
for project objects (if it does, then I am happy to use them), so I used
this (cons 'transient...) as a placeholder and a demonstration.

Another very similar way to go about this would be for joaot/sub-projects
to be named project-sub-products and live in project.el, where it would
be free to access its own internals.

(defvar project-sub-project-prefixes nil
  "List of strings designating sub-projects.
This variable should be set directory-locally.")

(defun project-sub-projects (dir)
  (let* ((super (project-current))
         (super-root (project-root super))
         (relative (file-relative-name dir super-root))
         (d (car (split-string relative "/"))))
    (cl-loop for prefix in project-sub-project-prefixes
             when (string-prefix-p prefix relative)
             return (cons 'transient (expand-file-name prefix
super-root)))))

Then it would be a question of setting project-sub-project-prefixes
to, say, '("lisp/progmodes" "test" "doc" "src") in Emacs's .dir-locals
(or using dir-locals-set-class-variables as an alternative).
