Yes. You are right. Thank you.
After thinking about I have found a better name:

(defcustom org-columns-checkbox-allowed-values '("[ ]" "[X]")
  "Allowed values for column with SUMMARY-TYPE that use checkbox."
  :group 'checkbox
  :type '(repeat string))

NEWS:
This would allow to use more than two states ("[ ]", "[X]") in
column with SUMMARY-TYPE that use checkbox ("X", "X/", "X%"). 
For example you can add an intermediate state ("[-]").
Or empty state ("") to remove checkbox.

What do you think?
