Resizing in sRGB has the advantage of obscuring ringing artifacts when enlarging images, because the nonlinearity puts more of them in the highlights than the shadows, where they're less obvious to human vision. You can get perceptually even better results when enlarging by using a sigmoidized colorspace. See:

For another clear example of the problems of resizing in linear colorspace, see "Catch #3" here:
