As you acknowledge, these three interfaces can be implemented using eachother. The higher level methods can use the lower level methods. There is nothing redundant there.

Nobody is suggesting that the OP should make one and only one interface available, except you (unless I am misunderstanding your position). Few users will have to "work around the supplied interface" if the interface embodies the common usage scenarios. That is the value-add.
