There are people who automatically dislike smooth water, HDRI, jpegs, etc. I don't and will judge each image to see what works and does not work. I care less about the technique used to get there than the looking at the effectiveness of the final product.
I use a lot of multi-image blending in my work, but find that I tend to shy away from ultra-long exposures for practical reasons. The Milford Sound image in the link you posted is because the landscape is static - the trees are so far away that any movement of leaves is imperceptible. Many of the places where I would normally shoot are "tree heavy" and long exposures give blurred leaves in the trees that are hard to avoid, so most of my long exposures tend to be a few seconds long, rather than minutes long to minimize leaf movement.
So, the technique does work in this case, as it smooths out some very minor disturbances in the water. If there are large disturbances and the exposure time is long, the opacity of the water would increase and the effectiveness of the shot would not be the same.
The one effect I often don't like in the long exposure images is the way movement in the clouds is affected. They tend to look stretched and all pulled and the linked image definitely shows that affecting the image.
