If a contributor wants to add new code, or fix bugs in existing code, 
they should not be increasing the use of existing deprecated mechanisms 
(after all we should be able to reasonably expect contributors to not 
make matters worse).  The prime motivator here should our joint goal to 
make GDB the best debgger possible, and more immediatly our desire to 
fix bugs such as those identified by my rewritten structs.exp.  As for 
other code, let it bitrot and die.

To give two tangable examples:

> The method get_frame_saved_regs() is obsolete. Changes should be decreasing, not increasing that function's usage count :-/ The new code will need to be written in a way that avoids this method. The best way of doing this is to convert it to convert that section of the code to the new unwind mechanism.

while I recommended using the new frame code, you'll note that I 
definitly didn't require it.  There were other ways of doing this that 
would have reduced the deprecated count that did not involve a frame 
conversion.

Similarly with the PPC and PPC64, you'll note that I've been fixing a 
depressing number of bugs in existing code, while at each step 
eliminating deprecated code.
