I agree with the author, that is a ridiculously short time for a breaking change in widely-used functionality. Every "update that breaks things" is teaching your users to not update the software, ever. Frankly, it's hurtful to users. By all means send the deprecation warning, but give a lot more time before removing the functionality. Tools require time to get widely distributed unless there's a huge emergency. In this case, there's no need for the hurry.
