Offshoot of bug#12159.

1. C-M-x the below defcustom.

 (defcustom vc-dir-hide-these-states '(up-to-date)
   "States hidden by `vc-dir-hide-some-states'."
   :type '(choice
           (const :tag "None")
           (set :tag "Choices"
                (symbol :tag "VC State" added)
                (symbol :tag "VC State" conflict)
                (symbol :tag "VC State" edited)
                (symbol :tag "VC State" ignored)
                (symbol :tag "VC State" missing)
                (symbol :tag "VC State" needs-merge)
                (symbol :tag "VC State" needs-update)
                (symbol :tag "VC State" removed)
                (symbol :tag "VC State" unlocked-changes)
                (symbol :tag "VC State" unregistered)
                (symbol :tag "VC State" up-to-date)))
   :group 'vc
   :version "24.2")

2. M-x customize-variable RET vc-dir-hide-these-states RET
3. You will see two "up-to-date"s and "added" is missing, from the
choices offered.

You're using it wrong.

elisp "Composite Types"

`(set TYPES...)'
     The value must be a list, and each element of the list must match
     one of the TYPES specified.[...]
     It is not possible to specify two different elements that match
     the same one of TYPES.

You probably want const rather than symbol.

Yes.  This is not a bug.
