I haven't been following these issues, counting on y'all to figure it out. :)

I'll just note that:

- I agree with your point about deprecation warnings.  IOW
   we should not check in new deprecation warnings on the trunk
   that cause warnings to be output when running the standard tests.
   We should correct any code that needs to be updated first.
   (Personally, I add the deprecation warning, making sure that I
   get the expected warnings, and then I make the warnings go away.)

- I think that dropping functionality should be considered carefully.
   I'm inclined to accept your judgement that the use cases need to be
   addressed.

Of course, we do want to move away from zLOG, as we want to leverage
the standard logging framework.
