Yes, this is an inconsistency. These commands are defined in
ly/property-init.ly:

[snip]
%% arpeggios

% For drawing vertical chord brackets with \arpeggio
% This is a shorthand for the value of the print-function property
% of either Staff.Arpeggio or PianoStaff.Arpeggio, depending whether
% cross-staff brackets are desired.

arpeggio = #(make-music 'ArpeggioEvent)
arpeggioArrowUp = {
  \revert Arpeggio  #'stencil
  \revert Arpeggio #'X-extent
  \override Arpeggio  #'arpeggio-direction = #UP
}
arpeggioArrowDown = {
  \revert Arpeggio #'stencil
  \revert Arpeggio #'X-extent
  \override Arpeggio  #'arpeggio-direction = #DOWN
}
arpeggioNormal = {
  \revert Arpeggio #'stencil
  \revert Arpeggio #'X-extent
  \revert Arpeggio #'arpeggio-direction
  \revert Arpeggio #'dash-definition
}
arpeggioBracket = {
  \revert Arpeggio #'X-extent
  \override Arpeggio #'stencil = #ly:arpeggio::brew-chord-bracket
}
arpeggioParenthesis = {
  \override Arpeggio #'stencil = #ly:arpeggio::brew-chord-slur
  \override Arpeggio #'X-extent = #ly:grob::stencil-width
  \revert Arpeggio #'dash-definition
}
arpeggioParenthesisDashed = {
  \override Arpeggio #'stencil = #ly:arpeggio::brew-chord-slur
  \override Arpeggio #'X-extent = #ly:grob::stencil-width
  \override Arpeggio #'dash-definition = #'((0 1 0.4 0.75))
}

As you can see, arpeggioBracket \reverts the changes taken for
tablature.
I think one quick solution would be to include this part in your
document and replace "Arpeggio" by "Staff.Arpeggio" to make
sure the changes apply to normal staves only.

Well, you can change the appearance for TabStaff.Arpeggio #'<some 
property> and
Staff.Arpeggio #'<some property> independently, but this could mean 
you'll have to
write some more shortcuts like the ones defined above for better usability.
