Sure, but what does the statement "Once deprecated this will become an 
error" mean? Will I have to use the -transition=intpromote switch 
forever to avoid an error?

Thinking about the fact that the deprecation doesn't show an error for 
the -transition switch, makes me think possibly the changelog message is 
incorrect.
