Thanks! I think you have a bit of misunderstanding of the :feature flag. You 
should only need to change

(defvar xxx-font-lock-settings
  (treesit-font-lock-rules
   :language 'xxx
   '(1111111111111
     2222222222222
     3333333333333)))

to

(defvar xxx-font-lock-settings
  (treesit-font-lock-rules
   :language 'xxx
   :feature 'minimum
   '(1111111111111)
   :language 'xxx
   :feature 'moderate
   '(2222222222222)
   :language 'xxx
   :feature 'full
   '(3333333333333)))

Ie, no need to create separate variables. And you should set 
treesit-font-lock-feature-list to

(setq treesit-font-lock-feature-list
      '((minimum) (moderate) (full)))
