It's present in 2.12.3 already (this is the oldest version I've installed)

Adding

\layout {
  \context {
    \Voice
    \alias "TabVoice"
  }
}

makes the following work.

\layout {
  \context {
    \Voice
    \alias "TabVoice"
  }
}

mus = {
  \override Voice.NoteHead #'color = #red
  \override TabVoice.TabNoteHead #'color = #green
  <c e g>4\arpeggio
}


\new TabStaff \new TabVoice \mus

\new Staff \new Voice { \clef "G_8" \mus }


Though, there's likely a reason why it's not the default _and_ it
returns an error if applied together with bend.ly.
Will investigate further.
