The workaround you suggested has a problem if the PlotMarker Circle[]  
is altered to a different radius.

ListPlot[{{{1, 1}}, {{1, 2}}},
  PlotMarkers -> {HoldForm at Graphics[{Hue[0.5], Circle[{1, 1}, 0.01]}],
    HoldForm at Graphics[{Hue[0.96], Circle[{1, 2}, 2]}]}]

Does not change the PlotMarker circle radius at all in either case.

This seems like a bug and I have reported it to WRI.
