MINFEATURESIZE is used only for labeling and makes sense when a polygons are clipped. It allows you avoid labeling slivers.

I've definitely try "label_no_clip" out. However, I don't think the MINFEATURESIZE if for me. The polygon as a whole is big enough for labeling, the problem is just that it's sliced into two parts. Having a min size limit on it may render the label gone at the edge, which is not the desire result.
