I think that there are probably three classes of inherited math code now. One class is the stuff that we kinda sorta plan to resurrect, another is the stuff that we will be replacing, but which is needed to avoid compile errors in class I and the final class is code that we really should delete.
Here is my classification of the remaining deprecated math code: Code to nuke now unless needed for compile: math/src/main/java/org/apache/mahout/math/GenericPermuting.java
