I'm not sure I understand this part. Do you mean something like this (set 
GUIX_PYTHONPATH in the let definitions)?:

(let* ((out (assoc-ref outputs "out"))
       (ibus-stt-dir (string-append out "/share/ibus-stt"))
       (guix-pythonpath
        (setenv "GUIX_PYTHONPATH"
                (string-append ibus-stt-dir ":"
                               (getenv "GUIX_PYTHONPATH")))))
  (for-each (lambda (prog)
              (wrap-program prog
                `("GST_PLUGIN_PATH" ":" prefix
                  (,(string-append (assoc-ref inputs "gst-vosk")
                                   "/lib/gstreamer-1.0")
                   ,(getenv "GST_PLUGIN_SYSTEM_PATH")))
                `("GUIX_PYTHONPATH" =
                  (,(getenv "GUIX_PYTHONPATH")))
                `("GI_TYPELIB_PATH" =
                  (,(getenv "GI_TYPELIB_PATH")))))
            (list (string-append out "/libexec/ibus-engine-stt")
                  (string-append out "/libexec/ibus-setup-stt"))))

In the meantime, I just sent a new version of the patch using git send-email to 
refresh my memory (haven't used it in years) and check whether automatic tasks 
are triggered in the infrastructure. The new patch amends the commit message 
and puts delimiters back. I will send another version later once I understand 
what is left to be done, together with the other patch to fix lint issues, as 
you suggested.
