The builder interface has important performance benefits over working with lists: similar to e.g. concatenating many small Strings vs using StringBuilder in Java.
The builder interface indeed does not need to be monadic, you can simply append things using <> and get the same benefits.
The monadic interface is purely a syntactic enhancement on top of that, to reduce the number of operators you need.
