I have always wanted this capability in order to make lakes look better. You are right in that it would only be for cosmetic purposes, and could only work on single, isolated polygons. But if you take a look at almost any commercial hard-copy map, the lake objects are all "smoothed". I believe the standard USGS 1:24k topo's have "smoothed" lake objects as well. My two cents...
