Okay, but it's easy enough to change, and people are getting a reasonable amount of time to deal with it.

I'm not dogmatic about things like this; warn() is just a hangover from a long time ago and bit of a nit, that's all. I suppose I should have removed it when 3.0 was released, but it went under my radar at that time.

Hence my post here, to get feedback from logging users about this proposed change.
