import mathutils
mathutils.Color([1,1,1,1])
Will give error, because it is expecting 3 values. But I guess now blender supports vertex, alpha so mathutils.Color should take 4 args?

Thanks for the report, but it's more a feature request.
Vertex color is not the only place which works with colors, some places will still only work with RGB (i.e. Diffuse color of closure).
Supporting 4 component color would be nice, but is not considered a bug.
However, adding on radars of @Campbell Barton (campbellbarton) and @Bastien Montagne (mont29).
