Btw, the IR stating:

  conditional-elements (array of grobs)
  Internal use only.

is a joke.

How so?  (I'm not familiar with conditional-elements.) 

OK, I think I see.  The description implies that a user would never need to bother with its contents--or shouldn't.  But access to the arpeggio grob is of potential interest.  Furthermore, there's no (convenient) documentation which would lead us to find it where it's now placed/hidden.

BTW, here's the relevant output for

{

  \override NoteColumn.after-line-breaking = #display-pointers

  <c' e' g' c''>\arpeggio

}

which shows Arpeggio in its new place and also serves as an illustration of the output of the functions earlier in the thread:

NoteColumn

 ((grob-interface

   ((axis-group-parent-X #<Grob PaperColumn >)

    (axis-group-parent-Y #<Grob VerticalAxisGroup >)

    (staff-symbol #<Grob StaffSymbol >)))

 (axis-group-interface

   ((elements

      #<Grob_array#<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob Stem > >)

    (pure-relevant-grobs

      #<Grob_array#<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob Stem > >)

    (pure-relevant-items ())

    (pure-relevant-spanners ())

    (pure-Y-common #<Grob NoteColumn >)

    (staff-grouper ())

    (X-common ())

    (Y-common ())))

 (note-column-interface

   ((note-heads

      #<Grob_array#<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > >)

    (rest ())

    (rest-collision ())

    (stem #<Grob Stem >)))

 (separation-item-interface

   ((conditional-elements

      #<Grob_array#<Grob Arpeggio > >)

    (elements

      #<Grob_array#<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob NoteHead > #<Grob Stem > >))))
