What I'm saying is that it would be nice to not break other  
activities with only a few hours notice. I happened to see the mail  
today, and I had time to change my activity right away. But I might  
as well have been away for a while, and whoever updated their  
machines in that period would see broken activities for no good reason.

I agree that you should not spend major efforts on backwards  
compatibility. But in this particular case it would have been easy, I  
guess in many more the same would apply. On a bigger change I'd  
expect a notice a few days in advance so we can cope with it in time.
