What about the special case of a table that is clustered on a column and all
subsequent inserts will add rows with ever-increasing values of that column?
This would be the case for creation dates or even a column created from a
sequence. Basically, after clustering, it would be nice if you could tell
the system to "only add to the end" and to "add in clustered order."

Programming for special cases is annoying, but sometimes it really helps.
