Depends if you want 1 size fits all or a dedicated sled. If 1 size fits all then you lose the ability for a clean backing fence. I have 1 for various segments and 1 only for 16 segments that is set without the ability to "skew" the segments but it has a high fence that extends past the saw kerf by about 1/5 inch. This allows for very little to mostly zero sanding of the segments.
A good friend made a sled with numerous "inserts" that allows for multiple number of segments by changing the insert
