I have no idea what you mean by "properly reflect increasing severity".  
Should the more severe or less severe case be derived from the other?  I 
doubt there is a single answer that we can readily agree on.

If DeprecationWarning and PendingDeprecationWarning need a class-hierarchy 
relationship (and I think they do; it *is* reasonable for someone to deal 
with them generically if they can reasonably want to deal with either), then 
it seems they need a common base:

  +--AnyDeprecationWarning
     +--DeprecationWarning
     +--PendingDeprecationWarning
