Thanks!

Only one feature request and some minor questions from me.

Can the project-list file name please be customisable?

Could the contents of the project-list file comprise easily readable,
printable, and even extensible sexps?

Could project-switch-project reuse read-multiple-choice or similar?

Isn't there a race here?

  (defun project--ensure-file-exists (filename)
    "Create an empty file FILENAME if it doesn't exist."
    (unless (file-exists-p filename)
      (with-temp-buffer
        (write-file filename))))

Why not use something like the following instead?

  (ignore-error file-already-exists
    (write-region "" nil filename nil 0 nil 'excl))

In fact, couldn't project--ensure-file-exists be eliminated altogether?
If the file doesn't exist, just don't set project--list, or set it to
nil.

Thanks,
