Rare use case? Have you seen any recent Java framework? Or Java EE 6? Or  
design by contract in C#? A declarative programming style can be very  
handy.

The fact that PHP is not C# or Java doesn't mean we shouldn't look for  
useful features in those languages, so it's not an argument. What you have  
to say is why you think annotations, while possibly making sense in C# or  
Java (depending on your position on that), do not make sense in PHP.

I also think you are overestimating the complexity introduced by this  
feature. The patch is not particularly complex. We have doubtfully useful  
features such as LSB which are more complex not only in implementation,  
but also in usage.

I though adding support for this was more or less consensual, and it was  
just a matter of tuning important but secondary details.
